Hello, I kinda have to use a BlackBerry as my primary phone for work. However, every time I've played with an Android phone I've walked away impressed and I really do want in on that OS's action. I'd actually prefer a tablet (along the lines of the Archos 101), but it looks like Android tablets are a bit away from being a mature, got the bugs out product. So, I'm considering buying an Android smartphone on eBay and just using it over wi-fi as a mini-tablet/PDA/iPod Touch. I have two questions: 1) Will this actually work, or will the thing be completely useless as a wi-fi only device? How stupid of an idea is this? 2) If I do end up loving the Android, how easy is it to upgrade/switch between Android devices as far as transferring all data and settings? Blackberry makes this super-easy with its desktop software - just back the old phone up onto your computer, and restore that file onto your new phone. Does Android offer anything similar between Android devices? It would be awesome if this functionality was so extensive I'd be able to switch from the smartphone to a larger Android tablet when that market matures. Thanks! P.S. The two devices that have caught my eye are the T-Mobile G2 and Sony X10 if you wanna weigh in on that too.
