Oh, I didn't know touch functionality wasn't the only limitation to what games were compatible. I just remember that being mentioned back when it first came out in Japan as Vita TV. In that case, I'd be even more sold on the Vita if I was trying to make the decision.

I can say that the one good thing with remote play for the PS TV is that you are still using a PS4 controller. I imagine it would play just like playing on a PS4 outside of possible lag and lower quality video. I still like the portability of the Vita and not being tethered to the TV if other people want to use it, but that's just me. As it is, my internet connection isn't really good enough for remote play anyways so that's all a moot point for me right now.
