It's an absolutely amazing handheld... IF you like Japanese RPGs and strategy RPGs. The thumbstick can be kind of irritating sometimes, but beyond that, it's a solid, comfortable piece of hardware with a pretty nice screen.
Having said that, the Vita is vastly superior in every way, so if you're not married to the idea of buying physical releases (many of which are getting $$$), the games will look considerably better on its OLED screen and be a little bit more comfortable to play.
