The Vita TV was shitty at everything it did, what a shame, my biggest gripes:
1. Remote play with PS4 is absolutely horrible, I have a pretty beefy network, and use other streaming solutions like the Steam Link and nVidia shield, but the Vita TV lagged like hell, could never use it.
2. It completely messes up your folders in the Vita if you are transferring back and forth a card from a Vita to the Vita TV.
3. and of course, the restrictions on most games, I just starting assuming that the games I wanted to play on it dont work.
In the end, I think I played like 3 hours of Super Meat Boy on it and never came back, it was just a frustrating device to deal with
