i just picked up a used 8gb wifi vita with uncharted and fifa for $210... I love the screen... but I'm disappointed in a lot of other areas... sorry if this sounds like a rant but:
the internet browser is rather crummy (re-size the damn page so I dont have to scroll right and left to read text!!!), there was noticeable delay for sounds when I used my bluetooth headphones for audio (it was at least 300-500ms consistently), having to remove that panel to switch games was annoying, remote play functioned, but the lag while playing PJ shooter made it difficult to play. The back touch panel for L2, R2 will take some getting used to... but I hope I can make it work. The lack of content on PSN store was also disappointing
Another thing I found odd was i tap a bubble...but to start the program, I have to tap the screen again?
Oh well, I'm going to play around with it for a few weeks and see what I think.... at the very least I think I can at least sell it for what I paid for it.
