Bought a Vita recently mainly for the PS4 Remote play functionality but I have found myself playing.
Super Meat Boy
Steam World Dig
and Tetris
I seem to have accumulated loads of games over the years with PS+ so should keep me going for a while.
I might even get round to using the remote play at some point!
Remote play was a pleasant surprise to me. I was heading away from home and didn't want to bring my PS4 with me so the vita worked a treat (been playing Destiny on it). Quite helpfully, they've remapped some of the buttons and whoever did it was an angel on earth.
In other news, I've also played quite a bit of Fez on it
