Can you use remote play without the ps4 being turned on? If not they list a very poor example of it's usefulness:"Yoshida-san makes the example of gathering, fishing, crafting or questing solo while relaxing on the couch on the PS Vita, and then, when the time for party play starts, one can switch to the PS4 to enjoy the challenging dungeon content on the big screen."

If your playing on your PS4 aren't you already on the couch? I mean I guess it would be nice for crafting while dropping a duece. Other than that what would remote play be good for? I plan on getting a PS4 and would like a vita as well but that's a lot of cash to throw down.
