Palm just announced the Palm Pre smartphone at CES 2009. It's a full touchscreen phone that slides open to reveal a keyboard.
It has Sprint EVDO rev. A, Wi-Fi, Bluetooth, a gesture area on the screen for navigation and use, a removable battery, micro USB, USB mass storage support, a 3.5mm Headphone Jack.
The phone is all touchscreen on the front, but it slides open vertically to reveal a keyboard that slides on a curve, kind of like the Xperia. It weighs 136 grams and can be used easily with one hand. The phone runs on a new platform named Web OS, which is designed to seamlessly integrate all your web content into one interface.
The phone itself reminds me of the Treo 680 in shape, except all there is on the front is a screen and a button.
One of the big new features is something called Synergy, which can pull contacts from all your sites (Facebook, Gmail, AIM, etc...), gather and organise them into one coherent list on the Palm Pre. It has dupe checking so you don't have the same contacts listed multiple times. It does the same thing for calendar events.
Web OS has been designed to work with your finger. All the demos are being done without a keyboard and stylus. Synergy can easily go from checking email, to scheduling meetings in a calendar, to IMing someone in your contact list.
