I lot people haven't experience Playstation Vita on the account of that it is currently more expensive that Playstation 3. They even avoid it because of the lace of software for the unit. Why spend that much, when there is nothing available for it? I bought for entertainment such as music (have no mp3 player) and for movies on the go (Digital Movies). I even surf the web and talk to my friend who has a playstation 3. I can understand the concerns people are having. I however; am having fun with the system, but it is rather limiting when only thing you can play are older Playstation Portable games. I've also heard that the Japanese consumers are now buying the system, but I'm assuming there must be games they want, that are going to come out for the Playstation Vita.
Edit button my friend, use it.
I'd get a Vita if I could afford it, I heard the software and hardware in that thing is amazing, being able to play Disgaea 4 on the go will be sweet too seeing as it isn't on a portable yet.
