ps vita for me..
I know nintendo's handhelds have a hell lot moar games and thats cool, but for me, the selling point 4 psvita is that it really delivers all that i want, a home console on my pocket (oddly enough, thats the weakness of the console sales-wise), is so wonderful to be able to play my psx classics without looking for the save points like i used to be, even ps3's games can be more convenient on psvita.
Also, ps+ is so damn sweet.
