I don't think Sony would, only for the fact people would buy it instead of the Vita, therefore cannibalizing sales. Too bad, because It would make on hell of a Nvidia Shield contender.They should just make an Xperia Play 2. hardware controls are the gamified user interface.
I was thinking something similar.. I would never use it, but I would put my parents on something like this in a heartbeat. My mom had the iPad Air for 6 months before I visited and held down the home button to look at the list of running apps. I had to scroll through like 30 pages of apps. Something like this, I assume, would help educate users about these features, instead of leaving them in the dark complaining about why its not working right until they call the 7 year old next door.This is a good idea for old people, or technologically illiterate type people. For us that like to explore our devices, and take them to the limits; it seems stupid
