Ultimate Mobile OS Showdown: iPhone vs Android vs webOs vs Blackberry vs Windows Mobile vs Symbian
Windows Mobile 6
The main story with Windows Mobile 6.1 is that the OS is fast, powerful, syncs well with Windows – but is seriously showing its age. Anyone who has used a Power PC or Windows Mobile device knows that it is hard to load apps, you never know which one will work, and that there is no app store yet. (Microsoft said they plan on adding a Windows Mobile Marketplace by the end of the year.) When there is touch control with a Win Mobile device, it seems like an afterthought compared to Palm Pre's webOS or the iPhone, occasionally forcing you to use a stylus (remember those?) and not always registering finger presses accurately. Still, the platform is rock solid in terms of reliability, and is much more compatible with enterprise-class systems – e.g., you can find specialized business apps for Windows Mobile that are not available for any other platform – than any other OS we tested.

The Palm Treo Pro we tested was obscured last month by the Palm Pre, but is still a capable phone. It uses a Qualcomm 400MHz processor and has 256MB of storage and 128MB of RAM. The phone has built-GPS, Bluetooth with enhanced data rate, a 320x320 display, Wi-Fi, and a 2 megapixel cam.
App Speed Test
Windows Mobile 6.1 speed varies wildly depending on the device. On the Palm Treo Pro we used, the OS was not nearly as responsive as the BlackBerry OS, especially for the core messaging and contacts apps. Both loaded in about 3-4 seconds. Some third party apps – such as Google Maps – took even longer, about 8 seconds from click to final map. The camera app was actually one of the faster-loading tools and loaded in about 3 seconds. Overall, the OS does not manage memory as well as the Android OS, which shuts down apps that are using too much memory. You can open 12-15 apps at once on the Palm Treo Pro, almost crippling the device, but the OS will happily load additional utilities. We'd prefer a warning when you have loaded too many apps or a way to manage them easier.

The Contacts app did not load as fast as similar clients on other platforms.
App Availability
While there are 20,000 apps available through outlets such as Handango, and you can likely find a plethora of Twitter clients and tools for switching between apps, they often lack the pizazz of an iPhone or Pre app. There is a good selection of games, many that have a desktop-like gameplay style such as real-time strategy variants for the small screen, but not any that are truly ground-breaking, such as HeavyMach on the iPhone, which uses the phone's accelerometer for moving your tank. We also did not find apps such as 8bittone or Leaf Trombone on the iPhone that offer new innovations. That said, being that Windows Mobile is a Microsoft platform, there are hundreds of powerful business apps such as Mobilis SyncStack (for access to a central database), and industry specific tools, such as MD Coder (for doctor's to record patient notes) and Mortgage Pad (for calculating loan amounts). There's also a wide selection of e-mail apps such as a Gmail client, and syncing tools such as Microsoft MyPhone.

Included games are dull and boring, but there are plenty of third-party games.

The new MyPhone app syncs data from your phone to a Web service.

First-party support for Word and Excel means Win Mobile is a great business OS.
Multi-tasking Support
Windows Mobile 6.1 supports multi-tasking, and on the Palm Treo Pro you can use a menu on the right side of the screen to access open apps and close those you do not need anymore. The OS does not manage these apps as well as the Android OS, and it is easy to load way too many of them at the same time not realizing that they have stayed open and are clogging memory. In one test, with ten apps open, the load time for commonly used tools such as the messaging app slowed to a ten-second load time.

the home screen does not show open apps, but you can access them using a menu in the upper right.
Media Support
Windows Mobile 6.1 is not as media-friendly as other platforms. For the most part, you can expect to use Windows Media files for audio and movies, JPG for photos, and MPEG-4 for movies – but the supported files varies by device. We tested JPEG and MPEG-4 on the Palm Treo Pro, but could not an uncompressed WAV file that worked fine on other platforms. One of the problems with Windows Mobile is that it is not aging well – there are at least 140 models that use the OS, and 57 mobile operators throughout the world, and each one seems to have a slightly different spin. This means, a video on a Sprint phone may or may not work on a Verizon phone. We prefer Android OS and the iPhone for media support because at least you know what will work and there is a standard route to take for buying new media content (such as Amazon MP3 and iTunes).

Our Palm Treo Pro played MP3 and windows Media files, but not WAV.
Organizational Tools
Once again, being a Microsoft platform, the PIM functions for contacts, schedule, and task management are top of the line – better than any other OS. Every Win Mobile device has a powerful contacts manager, scheduler, and task list that syncs easily with Outlook, and many Win Mobile devices include the Office Mobile suite for spreadsheets, docs, and presentations. These apps are predictable, reliable, and familiar although the Palm Pre has an edge in terms of combining schedules and contacts into one list. Windows Mobile seems unaware of trends in computing related to social networking, Web apps, and online data storage – most of the org tools are self-contained and do not work with online calendars such as those form Yahoo! and Google.

There's a search client in Windows Mobile 6.1 that searches across files and messages.
PC and Database Sync
Windows Mobile is a syncing powerhouse. There is a new client called Microsoft MyPhone that syncs to an online storage site, and both Windows Vista and the upcoming Windows 7 release support easy syncing between the mobile and your computer using Outlook. Win Mobile also offers a built-in remote access app to connect to your home server or work server.

Connect your Win Mobile device to a Windows desktop and you can easily sync files.

You can use a remote access client that works exactly like the desktop equivalent for network access.
Messaging
Windows Mobile places a strong emphasis on Outlook messaging – the built-in client operates like the desktop version with tried and true personal folders, spell check, plenty of messaging options of encryption and priority e-mail, and quick links to your existing Outlook or Hotmail contacts. There is a Gmail client, and the OS supports Microsoft Exchange (of course).

Text messages appear in the same messaging client as your ISP, Hotmail, or Webmail accounts.
Flash Support
Windows Mobile does support Flash Lite 3.0, but not the standard Flash used on most sites. Interestingly, while our test site for Flash Lite (www.gideonmobile.com) loaded part-way, it did not complete, which may just be a bug on the Palm Treo Pro for sites that support the older standard.

This site did not load with Flash but offered this served up this truncated mobile version.
Network support
The Palm Treo Pro supports HSDPA access and tested at 1Mbps, and the phone also works with the EDGE service. The Treo Pro supports 802.11g but not Bluetooth Stereo for audio.
Conclusion
Why is Windows Mobile last on our list behind Symbian OS and Android OS? It is a solid and reliable platform, one that has proven its merit in business time and again. The problem is that the OS has not kept pace with the times. Touch support is just not that adequate compared to an OS such as Palm Pre's webOS, Android, and iPhone OS that were built for touch control. The OS was primarily designed for a stylus, and the mobile market has moved on to touch apps. The OS is also not particularly fast, and while there is an incredible selection of apps, none of them are really jaw-dropping or innovative – they seem to be all stamped with “vintage 2002”. The OS has an outdated look and feel, is not Web-centric enough, and works differently depending on the phone you use.
