「Advent Chaos」

Yeah... I suspect that with 3G it could find its location like an iPhone. Near can tell its location from certain wi-fi access points, but not every suburban home will be able to give it whatever it needs to find where it is. No big loss, IMO. I still run into people when I walk around with it, and it shows me what they've been playing lately.

That is, no - the wi-fi only model definitely doesn't have GPS, but it's not totally lost either. I didn't think I'd find anything that supported it, but Near has reported a few addresses I've wandered past.

Go with the wi-fi Vita. My friend bought the 3G one and he has had literally no use for the extra functionality. Unless you use facebook or twitter a lot, neither will you. As a system, though, the vita is fantastic. If you want a game that will show off everything it's capable of, that would be Uncharted. If you're just looking for something fun and pretty, Rayman. Otherwise, the digital store has most of the PSP catalog, and they can be played with the right stick, too.
