I'd be mostly worried about user experience. A newegg comment said that google services don't work. I'm guessing that's gmail, google calendar sync, google talk etc.

I wouldn't be expecting many updates/after-sales support from this phone, so read some user reviews to see what works and what doesn't in practice. A listed feature (eg wifi) doesn't always work in practice (android 2.2, 2.3 had some issues with WPA encryption on some setups for example).

If it works and you don't care about being up to date with the latest OSes, it's good for 100 dollars when buying outright.
