I own a PS Vita, it´s a good thing and there are some fun (not so popular) games to.
Normally I listen to music on it and...actually I do everything ^^.
For the PS Vita are 5 WipEouts avaiable, the original, PurE, PulsE, 2048 and HD/Fury (don´t need to buy it again).
Also, there is a quiet cool alarm application (Wake-up club) and a tamagotchi-like game called "Ecolibrium".
I like the Vita, I even got anouther one, after I demolished my first one ^^
