So google just announced that they'll be shipping project glass early next year. The thing is, they hinted that out of the box it won't do much beyond take pictures. It seems that developers will have pretty open access to the device though. so that said: What do you want developers to make the device do? The only thing I can think of off the top of my head would be calendar notification sync from my phone, also the ability to dictate and write emails while walking.
