How about we just go to a north London Weatherspoon's, get wankered on cheap, shitty cocktail pitchers and Maker's Mark and then have a good cry in the park? That's pretty much how I usually spend my Thursday night anyway.
As someone who bought a Vita at launch, all I can say is NOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!! I literally haven't touched the thing in months, and am honestly unsure if I ever will again.
If you absolutely MUST have one, wait for both a price drop and for some good games to come to it that aren't either ports or available on another console. As of now, pretty much the only thing I can think of that falls into that category is Lumines.
