@OP. To play Uncharted streaming on a phone or tablet would be highly unsatisfactory without a DS3/4 controller, which means you need 2 devices with you to play the game on a mobile platform. Vita is a DS3/4 controller with screen attached, so far more convenient for PS game streaming, and some people are happy to pay for convenience.
If it wasn't for the fact my wife wanted a new phone, I was pretty much on my way to buying a Vita for remote play, and I still might if I find using DS4+phone to be awkward and frustrating. But I don;t remote play enough right now to justify a Vita purchase just for remote play purposes on an as needed basis. And aside from remote play I have no particular desire to do handheld gaming.
