Everything looks like a gimmick until it isn't. Even when the iphone was released nobody would ever be able to comprehend the reach it has today. I think we are waiting for hardware to "catch up" and its getting closer + people's aversion to wearing something like this (aka google glass .. prob too ahead) + the right ecosystem and company to take this to market (maybe apple is the one?).

For me personally I wanted to jump on board the spacial computing for reasons like being able to work in any location but have my awesome setup. Current systems have terrible resolution or are bulky, but I can see the promise. Current entertainment avenues are not tapped (imagine courtside sports seats anywhere, novel ways to engage users, porn, etc.)
