Yeah. People already sell laptops; this is basically a super expensive laptop with a fancy screen and a janky custom OS. But having this as an app for your phone, that let you pop other apps up into the heads-up virtual display or have "full screen" access to certain functionality while still supporting all your regular stuff, would be pretty different. So it can make your phone "laptop like" any time you wanted to pop the glasses on, or pop little notifications into the corner of your vision, maybe with a couple of little buttons on the glasses for "expand notification" "clear notification" "clear all" "up" "down" "minimize" "maximize", something like that, would be super neat. And then any time you want to break out the keyboard you can use it like a computer.
(I know the permissions and app compatibility and battery life etc would make that not necessarily trivial to do)
