Got my upgrade today. I was choosing between the HTC One X and the Samsung S3. Both are great, and in a couple of ways, the One X is slightly better (better keyboard app, better screen (graphics look like they're on top of the screen, it's insanely cool), better casing and looks), but the lack of removable battery and no SD expansion was the deal breaker for me.
Really happy with this so far. It's hard to imagine processors getting faster than this. You press something, it happens, with no lag at all. The HD display looks fantastic, too. Watching videos and gaming on this (neither of which I really do, but things actually look great on this, so I might start) must be cool.
Now to tinker with this mofo.
Makes my old Desire look inexcusably small.
Awesome, man. I'm trying to talk my girlfriend into getting that, like, tomorrow.
