I am trying everything out there - iPhones, Androids of many flavors - to try and find something that is "better" than a BlackBerry for me. Can't find it yet. Love the 9700, OK with the 9800, can't type a damn on the iPhone 4, Samsung Vibrant (Android) is OK but terrible battery life, and waiting for the G2 to come in.
Of course since one of my criteria is that the device runs Office Communicator, that limits anything not called "BlackBerry". Even Windows Phone 7 isn't shipping with OCS!
