Summary: I bought the ps vita in hopes of it being a great system with fun games and This year I was proven wrong. To me there are about 5 games that are good. This system has been out for almost two years and there is only about 60 games for it and the games that are coming soon are 10 that are officially coming out from now to January.
Summary: i got the psvita early in 2012 and it works good the touchscreen is amazing. the games that are out for it aren't that good though if your getting it i would recommend uncharted golden abyss you can download apps like youtube skype twitter and even netflix for free. it has a front and rear camera and front and back touchscreen. the browser sucks and the battery is ok. it fits pretty good in your hands and you can use a bluetooth to talk to people online.
Summary: The bad: No developers seem interested to make games that can be used between the vita and ps3. The browser is terrible, every time you scroll down, you have to wait for the screen to load. Using the browser, you can't watch any videos. If cost is important to you, than the system is pricey, compared to other handhelds, like the 3ds. The battery isn't anything to brag about either, when in "sleep mode" it dies in under 2 days.
Summary: While it has a very decent hardware, it fails to shine. First, web navigation is slow, facebook is much more faster in a cell phone. It has to load for everything, even to enter settings it has a little load time. In game load times are long, much more than in PSP, but once the game is running it's not annoying, you just have to wait a lot until you can play (at least on Disgaea 3 or Motorstorm).
Summary: The Vita is a great portable console, but Sony has made it so expensive to own that I have to wonder if a price cut is coming in the next few months. It's ridiculous that Sony created a new memory card format just for this system, rendering the memory cards used in PSPs useless. These memory cards are much too expensive. Also, the new game cartridge format means that any games you've purchased for the PSP will not work on this system.
Summary: The PSVita seems a cool handheld if you look at it from specs perspective. But lets break it down. PSVita does not support UMD which im sure a lot of the owners of the previous PSP wanted. Second, the touchscreen was not necesary, a nice implement but not necesary on a gaming handheld. The major difference i would have to point out is the second analog, but the cameras were not necesary in my opinion as well, A mic is fine. Third, the price is the same as a new PS3.
