The only hype worth looking is only the Android OS, nothing more.

looks like it should beat WinMob hands down. from the demo it should be a very solid OS for mobile use, backed by the Android community, stable operation, feature packed, and the hardware itself is a powerhouse. only the phone design is kinda awkward.
so yup, the android is kinda impressive, and it should be hundred times better than WinMob excluding some functions still missing on it like Exchange syncing. but being as an open source platform and backed by the community, looks like any shortcomings can be easily rectified either on next update or third party.
a very promising platform, but still early to decide whether it will be a successful platform or not. aside from that, the T-Mobile G1 looks ugly.
