Palm Treo 755p Cell Phone Review
|
Alfredo Padilla Published on December 20, 2007 Comment on this |
The Treo 755p won't be a surprise to anyone who knows Palm phones. We've seen the software and hardware on other devices, this just happens to be the first with this particular combination. Running Palm OS the Treo 755p is a powerful smart phone with excellent messaging and organizer features. Palm OS is as quick and easy to use as ever, making the Treo 755p a good choice for those who want the power of a smart phone without the learning curve that comes with Windows Mobile or Symbian devices. We like the small design changes made from previous Treo devices, removing the antenna, adding a soft touch finish and slimming a couple of millimeters off, but the Treo 755p is still a rather bulky device. Palm hasn't wowed us with a device for awhile and the Treo 755p does nothing to change that track record. The Treo 755p is available from both Sprint and Verizon. We reviewed the Sprint version of the phone that can be had for $249.99 with a two-year contract.
Tour & Design - We like the slightly revised design of the Treo 755p, but in a world of slim phones it's still a bit chunky.
Audio Quality - We saw some problems with audio quality on the Treo 755p, with sound sent and side tone both below average.
Imaging - The Treo 755p's stills camera had good color fidelity but very poor resolution. The video camera is very good for a cell phone.
Making/Receiving Calls - Making calls on the Treo 755p is simple and straightforward, but we wonder at the lack of voice dialing.
Messaging - Versamail is a decent email client, but it isn't BlackBerry good. On the other hand the SMS client is amongst the best we've ever seen.
Organizer - The Treo 755p provides users with powerful organizer tools and the ability to integrate with an Exchange server out of the box.
Multimedia - Music and video playback are both on board, but neither is anything special.
Software - Palm OS is powerful, fast and easy to use, but its also getting rather long in the tooth.
Battery Life - Battery life was average.
Connectivity - The Treo lineup still lacks Wi-Fi support, although Sprint's EVDO network might make up for this some.
Hardware - The Treo keyboard is still excellent and we found the controls easy to use as well.
Other Features - You can use the Treo 755p as a dial up modem for your laptop.
Value & Comparisons - At $249.99 with a two-year contract the Sprint version of the Treo 755p is more competitively priced than its Verizon counterpart, but we wonder why you wouldn't just go with the $100 Centro.

In the Box (4.5)
The Treo 755p ships from Sprint with a charger, USB data cable and a stereo headset in addition to the manuals and software CD. We found this to be a little on the light side, it would have been nice to get a start Mini SD card and perhaps a carrying case as well.
Handling (5.0)
The Treo 755p is easy to handle, with the curved back and soft touch paint making it feel very secure in the hand. This is in contrast to the plasticky construction on older Treo models. It is a little large and heft, however, so if you have to hold it up to your head for a long time you may get tired.
Portability (4.0)
Sans the protruding antenna that was found on older Treo model and with a few millimeters shaved off the Treo 755p is more portable than previous Treo's. At 2.3 x 4.4 x .84 inches and weighing in at 5.64 ounces it's not a lightweight. You'll definitely notice this phone in your pocket or bag, and it won't slip away easily if you're wearing tight pants.
Aesthetics (5.0)
The Treo 755p has professional good looks, just like it's older sibling the Treo 750. We like the blue soft touch finish and the silver accents, but we also realize that many people will look at the 755p and think it's boring.
Durability (8.0)
As was true of the Treo 750 the Treo 755p feels very solid. There were no creaks or obvious loose bits. The loss of the antenna means that's one less obvious point where you can break it. The soft touch finish also feels more impervious to scratching. A well built device.
[page title="Audio Quality"]
The quality of the audio you get during phone calls is one of the most important things about any phones. To test this we use professional grade equipment and software, which is often used by the manufacturers themselves. To simulate the human head and ear we use a Head and Torso Simulator (HATS) and to analyze the sound we use Listen Inc's SoundCheck software. For more information on how we test see this article.

Resolution (2.23)
To test the resolution of photos taken by the Treo 755p we take photos of an industry standard resolution chart and use the Imatest software to analyze the photos. Imatest produces a score called line widths per pixel height (lw/ph), which measures how many alternating black and white lines can be discerned before they start blurring together.

Color (6.36)
To test the quality of color in the Treo 755p's photos we take photographs of the industry standard GretagMacbeth color chart, which displays twenty-four different colors. These photos are then analyzed by Imatest, which compares the captured colors to those from the original chart.

Noise (1.17)
To test noise we take photos of the GretagMacbeth color chart at four lighting levels ranging from bright to very low. We then use Imatest to analyze the amount of noise produced at each lighting level. The Treo 755p performed middling in this test, although you'll note from the table below that there's not a lot of difference between the noise produced by cell phone cameras. Frankly they're all pretty bad.
| Cell Phone | Score |
| Palm Treo 755p | 1.17 |
| Palm Centro | 0.91 |
| Palm Treo 750 | 1.35 |
| BlackBerry Curve 8320 | 1.41 |
| T-Mobile Shadow | 1.23 |
| Sidekick LX | 0.76 |
Live Preview (7.5)
The live preview on the Treo 755p take up about three quarter of the screen with the bottom quarter showing you the various controls available. We found the live preview did a good job showing you exactly what you're going to get in the final photo. It also did a good job when panning, with very little blurring or pixelation. Interestingly, we found it a better live preview than on the Palm Centro or the Treo 750.
Unlocked Standby to First Shot (7.41)
We were able to go from the home screen on the Treo 755p to a new photo in only 2.7 seconds. This is a pretty good time for a cell phone, you can see below that the Treo 755p beat out all of its comparison phones in this test, including the Centro and Treo 750. We found that even though the camera took a moment to launch you could just hit the shutter button before it was fully up and it would start the shutter. This might make it a little hard to appropriately frame your shots, though, and if you need to wait for the camera to completely launch it will take a second longer.
| Cell Phone | Time (sec) | Score |
| Palm Treo 755p | 2.7 | 7.41 |
| Palm Centro | 3.8 | 5.26 |
| Palm Treo 750 | 5.77 | 3.47 |
| BlackBerry Curve 8320 | 2.9 | 6.90 |
| T-Mobile Shadow | 3.2 | 6.25 |
| Sidekick LX | 3.3 | 6.06 |
Shot to Shot Time (1.14)
Shot to shot time is a measure of how quickly you can take a series of photographs. When possible we use a phone's burst mode to do this test, but as the Treo 755p lacks this we had to do it manually. We did turn off the automatic preview so we could take photos faster. Under this situation we were able to take five photos in 13.2 seconds, which works out to 0.38 frames per second (fps). This is pretty slow, but as you can see below, a lot of phones are slow in this area. What this means is that you're going to have trouble capturing action shots, as that's where capturing a series of photos quickly is most important.
| Cell Phone | FPS | Score |
| Palm Treo 755p | 0.38 | 1.14 |
| Palm Centro | 0.28 | 0.84 |
| Palm Treo 750 | 0.61 | 1.83 |
| BlackBerry Curve 8320 | 0.35 | 1.05 |
| T-Mobile Shadow | 1.76 | 5.28 |
| Sidekick LX | 0.21 | 0.63 |
Shutter to Shot Time (4.65)
Shutter to shot time is a measure of how much lag you get between depressing the capture button and actually taking a photo. The Treo 755p did pretty well in this test with a shutter to shot time of 0.43 seconds. You can see in the chart below that this is tied for the best time amongst our comparison handsets. It's also significantly better than either the Centro or the Treo 750. What this means is that you won't have to hope your subject sits still for a long time, only about half a second.
| Cell Phone | Time (sec) | Score |
| Palm Treo 755p | 0.43 | 4.65 |
| Palm Centro | 0.88 | 2.27 |
| Palm Treo 750 | 0.88 | 2.27 |
| BlackBerry Curve 8320 | 0.43 | 4.65 |
| T-Mobile Shadow | 0.9 | 2.22 |
| Sidekick LX | 1.2 | 1.67 |
Interface (8.0)
Photo Album Software Internal (7.0)

Manual Control (0.0)
The Treo 755p doesn't offer you any manual controls for your camera.
Zoom (1.0)
The Treo 755p has a simple 2x digital zoom available for photos. All digital zooms are of limited utility as all they do is crop and enlarge what you're seeing, which is no different than what you might do with software on your computer.
Focus (0.0)
The Treo 755p has a fixed focus camera. Most cell phone cameras are fixed focus, but for a higher end device like the Treo 755p we wish that they had included a higher end auto-focus camera. While we're at it we'd also like more than 1.3 Megapixels too.
Flash (0.0)
The Treo 755p doesn't have a flash.
Metering (0.0)
The Treo 755p doesn't offer any metering controls, not even simple brightness adjustments.
White Balance (0.0)
Most cell phone cameras offer you some basic presets for white balance, but the Treo 755p lacks even these.
Image Handling (3.0)
There are some basic image handling options on the Treo 755p. You can add an audio caption to an image, rotate it or draw on it. You can also add text boxes to the photo. There's no support for more advanced options like red eye correction, color correct or resizing images.
Video
Overall Video Score (6.0)
The video produces by the Treo 755p is pretty good quality. It's captured at 352 x 288 and 15 frames per second, which is better than any phones but high end Nokia devices like the N95. The video is good enough to use online like on Youtube and will even look decent on a computer monitor at full screen. We wouldn't recommend trying to view it on a big screen TV though.
Video Resolution (6.72)
To test video resolution we take a video of the same resolution chart we use in the still camera test. We then run frames from this video through Imatest to produce a line widths per pixel height (lw/ph) score. This score tells you how many alternating black and white lines can be discerned before they start blurring together. Confirming our good impression of the Treo 755p's video capture it did well in this test scoring 242 lw/ph horizontal and 272 lw/ph vertical. You can see below that it put up the best score amongst our comparison phones, handily beating out both the Centro and the Treo 750.
| Cell Phone | lw/ph horizontal/vertical | Score |
| Palm Treo 755p | 247/272 | 6.72 |
| Palm Centro | 249/274 | 6.82 |
| Palm Treo 750 | 132.4/184.6 | 2.44 |
| BlackBerry Curve 8320 | n/a - no video recording | 0.00 |
| T-Mobile Shadow | 155/168 | 2.59 |
| Sidekick LX | n/a - no video recording | 0.00 |
Video Compression (2.0)
Video on the Treo 755p is captured in 3GP format, which is fairly standard for mobile devices. There are no alternative options available.
Interface (7.5)
The Treo 755p's video interface is pretty much the same as the stills interface. The top of the screen is still the viewfinder while the bottom is given over to controls. There's no zoom control for video capture, instead up/down on the D-Pad are used for pause and stop. All the other shortcuts are the same and the counter is replaced with a timer showing you how much video you can capture.
Manual Control (0.0)
There are no manual controls for video capture on the Treo 755p.
Zoom (0.0)
Unlike the stills camera there's not even a digital zoom for video capture on the Treo 755p.
Editing (0.0)
You can't edit videos on the Treo 755p.
Modes (0.0)
There are no specific modes on the Treo 755p for capturing MMS or email video.
[page title="Making/Receiving Calls"]
Dialing Speed (6.10)
The Treo 755p took an average of 3.28 seconds to dial a phone number. This is pretty good, you can see below that only the Curve beat out the Treo 755p's time in this test. We did find the number keys on the keyboard to be a little small and occasionally prone to errors. Unfortunately, it's just something users will have to have to get used to. To do this test we time how long it takes to dial each of five test numbers, starting from the home screen and ending when we hit the send button. | Cell Phone | Time (sec) | Score |
| Palm Treo 755p | 3.28 | 6.10 |
| Palm Centro | 3.62 | 5.52 |
| Palm Treo 750 | 4.25 | 4.71 |
| BlackBerry Curve 8320 | 3.16 | 6.33 |
| T-Mobile Shadow | 3.44 | 5.81 |
| Sidekick LX | 4.2 | 4.76 |
Talk and End Buttons (7.5)
Unlike the Treo 750 where the send and end buttons were located to the far left and right of the D-Pad the Treo 755p has them in a position that will be familiar to Palm OS users, just below the screen to the left and right of the D-Pad. On the 750 these buttons are used for the soft key functions but Palm OS lacks soft keys. We like this positioning better for making calls as the buttons are larger and easier to find by feel than those on the Treo 750. They provide good key travel when pressed and solid tactile feedback.
Call Management (6.0)
Call management features are typical Palm fare. During a call you have several buttons on screen to access functions like speaker phone, hold, the dial pad, and mute. The menu key brings down a menu with a few additional options, like connecting to a Bluetooth headset. There's no support for recording a phone call. The call log on the Treo 755p is a chronological list of phone numbers. You can filter by incoming, missed, or outgoing calls. When you have a call selected you can use on-screen buttons to add that number to your contacts or view details for the call. There was no information about total call timers or data transfers available. As with most Palm devices when your call ends the Treo 755p will ask you if you want to add the number to your contacts if it's not already there.
Startup to Call (2.38)
This test measures how long it takes to get a phone going from being totally off until we're able to dial a number. We use the same five test numbers as we did with our standard calling test. As with other Palm devices there's no way to completely turn off the Treo 755p without taking out the battery, so this test is a little less relevant than other phones that actually have an off switch. The Treo 755p took an average of 42.1 seconds to start up and make a call. This is a decent time for a smart phone. As you can see below most of our comparison phones did pretty poorly here too. The only exception is the Curve that, like all BlackBerry devices, is very quick to start up.
| Cell Phone | Time (sec) | Score |
| Palm Treo 755p | 42.1 | 2.38 |
| Palm Centro | 42.66 | 2.34 |
| Palm Treo 750 | 42.26 | 2.37 |
| BlackBerry Curve 8320 | 7.12 | 14.04 |
| T-Mobile Shadow | 78.36 | 1.28 |
| Sidekick LX | 56.54 | 1.77 |
Ring Volume (84.9)
The Treo 755p's ring volume measured 84.9 decibels. As you can see below this is pretty standard, with all our comparison phones falling within a couple of decibels. It's the rare phone that deviates from the 80-90 decibel range in ring volume. To make this measurement we go through all the phone's ring tones at maximum volume and use a sound pressure meter to measure the loudness.
| Cell Phone | Volume (decibels) | Score |
| Palm Treo 755p | 84.9 | 8.49 |
| Palm Centro | 85.5 | 8.55 |
| Palm Treo 750 | 83.2 | 8.32 |
| BlackBerry Curve 8320 | 85.6 | 8.56 |
| T-Mobile Shadow | 85.4 | 8.54 |
| Sidekick LX | 84.5 | 8.45 |
Ringtone Customizability (2.0)
As we've seen on other Palm OS devices the Treo 755p doesn't allow you to use your own music files as ring tones. You instead have to turn them into MIDI files and go through a convoluted process to get them on the phone. We won't be awarding points for that. You can use your own voice recordings as ringtones, however.
Non Audio Alerts (8.0)
We found the Treo 755p's vibrate a little on the light side, but better than that on the Treo 750. As you would expect the Treo 755p's screen lights up when a call comes in, and perhaps more helpful, the LED indicator will blink when you have missed a call.
[page title="Messaging"]
Supported Email Services (7.5)
As we've seen from other Palm OS devices Versamail is the principal email client on the Treo 755p. Versamail supports POP3 and IMAP4 email services. It also makes it easy to set up a variety of popular email services like Gmail, AOL and Yahoo.
Push Email (3.0)
The Treo 755p supports Push email via Activesync with an Exchange account. There is also a BlackBerry connect client for Palm OS available, but this doesn't come standard on the 755p.
Multiple Email Accounts (10.0)
The Treo 755p supports more than five email accounts, although it can only support a single Exchange account at a time.
HTML and Attachments (4.0)
HTML email is still not supported by the Palm OS platform, so you might get a bunch of gobbledygook when you go to open an HTML heavy email. You can view and edit Word, Excel and Powerpoint documents as well as view PDF documents via the included Documents2Go software. There's no support for zip files, but there are plenty of third party programs that will add this functionality if you need it.
Email Customizations (5.0)
The Treo 755p allows you to choose from three display fonts, with some of them providing multiple font sizes. You can also create signatures for outgoing emails and decide whether to view messages in your inbox on one or two lines. All in all a good selection of email customizations.

MMS Support (9.0)

SMS Smiley Face Interpretation (10.0)
Those who love smiley faces love Palm devices, and for good reason. Not only does the Treo 755p's excellent text messaging application turn smileys into their graphical equivalents, but they also make it very easy to insert a smiley from a small pop up menu. Very well done.
SMS/MMS Ease of Use (8.0)
The Palm OS SMS/MMS messaging application is one of the best we've seen on any phone. Not only is there no unnecessary separation between SMS and MMS messages but its also very easy to use. Especially with the threaded messaging feature that organizes your SMS messages into conversations. Many people may have become familiar with this because the iPhone does it, but it was actually Palm that did it first and still, in our opinion, does it better. Time to a New SMS Message (11.11)
Like all Palm OS devices we've reviewed the Treo 755p is very quick at getting a new SMS dialogue on screen at 0.9 seconds. You can see below that the only comparison phone that competes with the 755p was the Palm Centro, with all the other phones putting up good, but not quite as spectacular times. To do this test we time how long it takes to go from the home screen unlocked until we have a new SMS dialogue on screen. With the Treo 755p we just tap on the messaging button and then tap on the new button on screen. Power texters will love how easy this is.
| Cell Phone | Time (sec) | Score |
| Palm Treo 755p | 0.9 | 11.11 |
| Palm Centro | 0.86 | 11.63 |

[page title="Organizer"]
Synchronization (8.0)
The Treo 755p comes with HotSync, which is Palm's desktop synchronization software. HotSync is easy to set up, just install the software, connect your device and touch the HotSync button on the cable. You'll quickly find all of your information synchronized between the 755p and your computer. The Treo 755p can be synchronized with your computer via USB cable or Bluetooth. Contacts, calendar appointments, tasks, notes and email accounts are all taken care of.
The Treo 755p can be synchronized with Outlook on a PC or you can use Palm's own PIM management software. The Treo 755p an also be synchronized with a Mac right out of the box, although this doesn't offer you as comprehensive a range of support as PC synchronization does.
Alerts (7.0)
Calendar appointments and tasks are the only items on the Treo 755p that can have an alert set. The alert can be set to go off any time before the appointment/task occurs. You can't set individual tones for each appointment/task, instead the standard one you set up will be used for all alerts. When an alert goes off you can choose to view, dismiss or snooze the item. A snooze only lasts for five minutes and there's no way to change that. When an alert is missed it will go off again based on a preference and if you miss even that it will be the first thing you see on screen when you turn the phone back on. We prefer the flexibility that Windows Mobile alerts give us over snooze, but aside from that the Treo 755p's alerts are solid.
Over the Air PIM Sync (2.0)
The Treo 755p supports synchronization of your contacts and calendar appointments over the air if you have access to an Exchange Server.
Address Book
Adding Contacts (8.47)
It took us an average of 11.8 seconds to add a contact to the Treo 755p. This is a very good time, in fact it's the best time amongst our comparison phones, as you can see below. It's slightly better than the Palm Centro, which is probably due to the Treo 755p's bigger and more comfortable keyboard. To do this test we time how long it takes to go from the home screen unlocked until we have added each of five different contact names and phone numbers.
| Cell Phone | Time (sec) | Score |
| Palm Treo 755p | 11.8 | 8.47 |
| Palm Centro | 12.22 | 8.18 |
| Palm Treo 750 | 16.1 | 6.21 |
| BlackBerry Curve 8320 | 14.1 | 7.09 |
| T-Mobile Shadow | 21.88 | 4.57 |
| Sidekick LX | 19.58 | 5.11 |
Looking/Sorting/Search (5.5)
The Treo 755p allows you to sort contacts by last name or company. You can filter your contacts by category and search for them simply by typing out the name (or company if that's your sort option) on the QWERTY keyboard. We would have liked the option to sort by first name, but otherwise are satisfied with the features here.
Fields (8.0)
The Treo 755p has 30 different fields available for contacts, including user-customizable fields where you can put whatever you want. The total number of fields is less than what we see from Windows Mobile devices, like the Treo 750, but those lack user-customizable fields.

| Sidekick LX | 12.44 | 8.04 |
Calendar Views (7.1)
As with all Palm OS devices the Treo 755p has five calendar views. By default you find yourself in daily view, which shows the day's hours along the left side with your appointments blocked out at their scheduled times. The weekly view is a typical grid with days along the top and hours along the left. In this view you get a small pop-up that shows you appointment details for the day that is selected. This is a nice touch as many weekly views just show you time blocked out with no appointment details.

The monthly view is just the current month with a small box on days that have appointments. The yearly view is just useful for an overview of the year and shows six months at a time. It can only be accessed via the menus. The agenda view is much nicer, it shows you a list of appointments and adds tasks and unread emails. You can easily cycle between all the views except yearly by repeatedly pressing the calendar button.
Fields (11.0)
The Treo 755p offers a good selection of fields for new appointments, including all day appointments, time zone, categories and recurrence. The interface for creating a new appointment does take some getting used to as it's divided into two parts. The first allows you to set start/end time and other time-related options. Once you do that you enter the title and only then can you open the appointment up and add more options. We would have preferred a single interface as found on Windows Mobile devices.

ToDo/Task Sorting and Prioritizing (7.0)

Fields (7.0)
New tasks on the Treo 755p allow you to add a title, priority, category, alarm and due date. You can also add a recurrence pattern, which is a nice option that isn't found on most phones. Overall, we were happy with the range of fields available for new tasks.

Dedicated Music Controls (1.0)
Aside from the volume keys, which of course control volume, the Treo 755p doesn't have any dedicated music controls. These are controls that relate to music functions while on the home screen. You can set a preference in pTunes to have one of the buttons on the device bring up the program when music is playing, but this is turned off by default.
Music Software Functionality and Organization (8.0)

Online Song Downloading (0.0)
Like the Palm Centro from Sprint the Treo 755p does not support their music store. We know that the device supports Java programs so the DRM must be the issue here.
Streaming (4.0)
The Treo 755p supports streaming audio in Mp3 and Windows Media formats, but not Real.
Podcast Support (0.0)
The Treo 755p doesn't have any software to download or organize podcasts.
Music Sync with PC (7.0)
Music can be easily synchronized with a PC using the standard Windows Media Player interface. The memory card on the device is recognized by the software and you can set up sync lists or just move music back and forth manually.
Music Formats and DRM (3.0)
The Treo 755p supports AAC, Mp3 and WMA music files but doesn't support any form of DRM protected music.
Music Interruption (10.0)
If a call comes in while you're listening to music the Treo 755p will handle it like a champ, pausing music automatically and starting it up again when the call ends.
Video
Video Software Access (6.90)
The Treo 755p took only 2.9 seconds to get a video playing, which is a very good time. Once again we used keyboard shortcuts to jump near the Pics & Videos software, then just navigate over and hit the select key three times to get a video playing. Also familiar is the Treo 755p topping our list of comparison phones in a timing test, as you can see below.
| Cell Phone | Time (sec) | Score |
| Palm Treo 755p | 2.9 | 6.90 |
| Palm Centro | 3.16 | 6.33 |
| Palm Treo 750 | 6.88 | 2.91 |
| BlackBerry Curve 8320 | 8.08 | 2.48 |
| T-Mobile Shadow | 8.92 | 2.24 |
| Sidekick LX | n/a - no vide playback | 0.00 |
Video Controls (4.0)
Video playback on the Treo 755p is handled by the album software and the controls are pretty basic. Videos automatically go into full screen mode, although most videos aren't formatted for the Treo 755p's square screen so there will be bars above and below it. The volume keys control volume, of course, and the center select button stops playback and takes you back to the album screen. Left and right move to the next or previous video while up/down reveals on screen controls that are no different than what you can do with the hardware keys. Phones with more dedicated video software like the Curve or Treo 750 provided better options for video controls.
Video Software & Organization (1.5)
As we mentioned above the Treo 755p uses the album software for video playback. This means that the features are limited. There's no support for ratings, playlists, background play or library organization. Anyone who wants to organize and watch a lot of videos on the Treo 755p should consider some alternate software like Coreplayer.
Video Sync with PC (7.0)
Just like music you can use Windows Media Player on your PC to synchronize video over to the Treo 755p.
Video Formats (4.0)
The Treo 755p was able to handle 3GP, Mpeg-4 and H264 encoded video. It wasn't able to handle other file types like Quicktime, Flash, Windows Media Video or Real.
Video DRM (0.0)
The Treo 755p can't handle any DRM protected video like those purchased from iTunes or Amazon's Unboxed.
Video Playback Smoothness (10.0)
The Treo 755p was able to handle all five of our test videos up to 768 kbps. This means it can play back pretty high quality video, which only makes the poor video software even more frustrating.
Online Video Downloading (0.0)
The Treo 755p does not support any direct video download services.
Video Streaming unscored
We don't score this this section because there's really no standard for streaming video to mobiles. We do test some popular sites to see if they work, however. We were very pleased to see that streaming 3GP video from zoovision.com and Youtube Mobile both worked, as did streaming Windows Media Video from windowsmedia.com. Sprint also offers a wide variety of pay streaming services via the Sprint TV program.

OS (8.0)
The Treo 755p runs the latest version of Palm OS. Of course the word "latest" there requires some explanation. Palm OS hasn't been upgraded for years, so "latest" is actually pretty out of date. Rivals like Windows Mobile and Symbian have gone through several iterations while Palm OS has essentially stood still. Palm is working on an updated version of their OS that is supposed to be out in late 2008 or early 2009, but given their struggles lately you have to wonder if that will ever see the light of day.
Criticisms aside, Palm OS still does deliver a lot of value. Despite not seeing a significant upgrade in awhile it still performs admirably in several departments, including ease of use and responsiveness. Users will be able to pick up the Treo 755p and start figuring things out on their own. It also provides more than enough power for most users and is very extensible with literally thousands of third party applications available. Despite being long in the too the Palm OS is still a worthy buy for those who are looking for an easy to use smart phone experience.
Home Screen Score (4.0)

Extensibility (6.0)
Palm OS is one of the most extensible platforms out there with thousands of native third party applications available for installation. Unfortunately the Treo 755p doesn't support java applications out of the box. Instead you will need to install a separate java virtual machine to install and use java programs. This is in contrast to Symbian devices that run Java applications natively.
Customizability (6.0)
The Treo 755p is not as customizable as other platforms. We've mentioned many of the customizations you can make already, including the ability to categorize and filter your applications and assigning applications to a long press of any letter key on the QWERTY. You can also choose from various "themes", which really just change the color scheme of the interface. Compared to other phones that have themes that change the whole look and feel of the device these are just not very impressive.
OS Responsivness (9.0)
Despite being long in the tooth, Palm OS is still one of the fastest operating systems we've seen on any phone, much less a smart phone. It runs circles around Symbian and Windows Mobile and is even faster than the iPhone interface.
Browser Features (8.0)

Browsing Interface (3.5)


Browser Access (8.00)
It takes five steps to launch the web browser and open a specific page on the Treo 755p. As you can see below, this is pretty good. Only the Sidekick LX did better in this test than the Treo 755p did. We count steps in this test instead of using a timed test because we don't want network issues to interfere with the score.
| Cell Phone | Steps | Score |
| Palm Treo 755p | 5 | 8.00 |
| Palm Centro | 5 | 8.00 |
