So, some good came from the malfunction of my vita screen. I bought another one right away (CoD bundle lol), and now I'm using my account on both and playing (Soul Sacrifice , Rayman Legends all Ad-hoc) with my friends. I'm downloading Dragon's Crown on my second vita to try it too.
Two of my friends are thinking of getting a vita (one along side PS4) because we had fun playing Soul Sacrifice ad-hoc.
