I'm going to wait a couple years at least, right now it's too much of a prototype and no multitasking kills it for me personally. I can see a device like this being used for many daily activities it's just way too early in the design stage for it to be useful. Take the idea of including a high resolution camera; you could hold up the large screen and frame your shot like no other camera out there, perhaps by then post-processing on the fly with your favorite filters etc.
Also notice how the older TVs were all round, when these gizmos go square that's when it starts to get real!
