So far I must say I am enjoying it. The Google integration is flawless (What else did you expect). When loading the sim for the first time it asks you for a Google account a few seconds after authentication all your contacts calendar and emails are all synced down to the phone. The contact sync feature to me was the greatest since my old phone had gone to mobile heaven.
Their UI is by far one of the easiest to use and most intuitive. I have only tried out the Apple’s Iphone but so far the fact this phone as a qwerty keyboard makes it easier to use. This does take some getting used to I still feel I type faster on the standard 9 key mobile keypad then this smaller qwerty one.
Hopefully in the next while I will be able to check out their SDK and put together some sort of app. For now I guess I will have to just live with a super cool phone.
Word of note the the synchronization can kinda kill your battery life but all of this is easily turned off or configured to happen at a less frequent interval.
