Ultimate Mobile OS Showdown: iPhone vs Android vs webOs vs Blackberry vs Windows Mobile vs Symbian
Organizational Tools
We think webOS is the killer OS for keeping you organized because it's so easy to use, supports multi-tasking between PIM apps, and supports copy and paste so you can grab an e-mail, copy the contact info, and paste it into a task list in just a few steps. Only BlackBerry OS offers more PIM tools and more advanced features, but they are not nearly as easy to use as they are on the Palm Pre.

Not every smartphone OS includes a task manager, but Palm – who created the PIM handheld – does.

With post-it memos, you can add reminders or notices to a bulletin board.
PC and Database Sync
When you connect a Palm Pore to your computer, you will see three options: you can just charge the device, use a media sync mode, or access the USB drive. At the time of this writing, with iTunes 8.2, the Pre still connected for media sync as though it is an iPod, but Apple has hinted that this spoofing might not last for long. As it is, adding music to the Pre is easy with iTunes, and you can drop movies and photos onto the device easily enough using USB mode. The OS uses Microsoft Direct Push Technology to sync your Exchange messages automatically, and Web e-mail syncs as well.

Syncing works exactly like it does on Android – by making sure Web apps and smartphone are in line.
Messaging
Messaging on webOS is a major plus. The OS feeds contacts in from Gmail and Facebook and makes them all available from one messaging app. The only gripe here is that, if you have a lot of “fake friends” on Facebook, their contact info will clutter up the client and make it hard to find the one you want. Fortunately, webOS battles this nightmarish scenario with a slick search function. You can start typing a name at any time on the home screen, and webOS will search for that name. So there is little need to ever scroll through several hundred names. The OS also unifies messaging into one screen with all SMS, MMS, and IM messages in one place for easy viewing and reply.

WebOS automatically shows all SMS, MMS, and IM message son the same screen.

Adding Gmail and Facebook contacts means you can compose new messages faster.
Flash Support
The Palm Pre webOS does not support Flash. Like every other phone except the Nokia N97 running Symbian S60 Fifth Edition, does not support Flash Lite either.

WebOS does not support Flash, but did format sites that use Flash correctly by using static images.
Network Support
Since the only phone that runs webOS is the Pre, and it uses Sprint, the 3G network access is EV-DO Rev A, which ran at about 1Mbps for Web browsing and e-mail. WebOS also supports Bluetooth Stereo and – for surfing over a hotspot – 802.11g Wi-Fi, but not the more recent 802.11n.
