The vita doesn't actually have the hardware inside it to be as powerful as the PS4, but it can do the same thing as the Wii U using the remote play thing. This means the game is played on the vita, but it isn't actually /run/ on the vita. You need a PS4 available to have the software running.
Also, I'm not saying that Sony copied Nintendo, because the remote play thing's been around for ages.
Yeah I have a vita.
There's only 1 glitch I encounter now:
When I clean the screen, the screen glitches and moves around stuff, to fix it-I have to turn it of and back on.
if I lose charge with say, Terraria and Youtube on, I can re-charge it and get back to what I was doing.
Also I dropped my Vita so we got a new one because of some policy that we'd get it back if we broke it within about 2 years.
