I love the vita! its very inexpensive and it still gives you good quality game time. There are a lot of good games that still come out all the time,Especially if you like rpg games and there are also ps vita ps2 and ps1 games on ps vita there is literally thousands!

its very nice to have and the battery last for a long time. It has twin joysticks a camera, gyroscope, touchscreen and a rear touch panel. you can also play multiplayer games. you might not think much people play the vita online but that is where you are wrong. You can find groups and communities of strictly ps vita players i always find people to play online with.
another cool feature is you can use remote play on the psvita. This allows you to stream your playstation 4 games directly to your Ps vita. as long as you have a good internet connection it should all work great with no lag.
I suggest buying the vita it still has alot of life to go and plenty more games to come out.
