There are things I'd want to use it for, but notifications are not it. Map overlays, video chat (with a better camera), and of course outright augmented reality. At some point, the display will be integrated in the actual glass and will be able to pick a different focus distance for every pixel. Add in sufficiently powerful mobile computers, and you have full AR. When that happens, Glass (or its successor) will become truly indispensable; this is just the birth pangs. Might be a decade or two, though. It's a tall order; molecular nanotechnology could construct a device like that, but I'm not convinced we'll be clever enough to do it before that point.
