I'm surprised that so few people have tried out remote play. It's pretty awesome, although it is not well suited for all games. Resogun and KZ are playable but not as good, but games like Don't Starve that aren't that sensitive to perfect accuracy are great. As we get more RPGs and slower-paced games it's going to be really great.
The back touch pad is my only complaint about the Vita. It's not comfortable to hold it on the little oval pads. They need to let us select the active zones, like letting so that you have to touch near the middle to activate it. Or let us change the input, like letting a swipe be registered as a button press. That way you can hold it more comfortably but still take advantage of the touch pad.
Still, I'm glad that the PS4 seems to be helping the Vita a bit. It's an awesome little system.
