WOW, I tried the Vita's remote play last night, and I must say I was very impressed. The only real short coming I experienced, was the lack of L2/R2 buttons. They offer decent enough alternatives, but like anything, it's a lesser substitute to the originals.
I only tried ICO, and that is a less graphical work horse to SOC, but it ran flawless for the short time I played it. Sony really should promote this feature more. I guess with the PS3, there aren't to many titles that the support the feature, and really only Sony can be blamed for that, but if this works with 95% of PS4 titles, I may be getting one sooner than planned.
In my advanced years, it just gets harder and harder to spend time in front of the BIG TV for game play time. I currently don't even buy LIVE/PSN titles anymore, as I just never get around to playing them. If a new title like Ducktales remastered isn't offered on Vita, but then I could play it through remote play, that would be very cool.
Although I haven't gotten a WiiU yet, one of the best features for me, is being able to give the controller to my son, so he can play games, while me and the wife watch some shows. So I really don't know how much this feature means to the masses, as WiiU and Vita sales currently suck(Nintendo & Sony haven't done much promotion for this feature), but for me it is a really cool feature that I would love to use more of in the future.
