Glass is the headset display analogue of Microsoft's early tablets. It's not likely to be a blockbuster consumer product this year or maybe not next year but moving displays next to our eyeballs is a natural next step and putting cameras on headsets is a natural next step. I'm hugely skeptical whether those steps need to happen together. I'd guess the killer app for next gen mobile headsets is the ability to record your surroundings. Yes you can do that with a phone today. What you can't do is have your phone in your pocket constantly holding 5-15+ seconds of audio and video so that when you hit record you get the thing you actually wanted to record whether it's something adorable your kid/pet did, a great joke, an illegal act etc. So that's the killer app imho and it's going to require an insane amount of battery life up front (and we're putting it right next to people's brains so it better not catch fire or blow up). Then we'll probably need an insane amount of mobile bandwidth and cloud storage for persistent streaming. But wait we're jumping ahead, you don't need an eye display to do this, you get the functionality from just a camera on a bluetooth headset while the slab in your pocket handles the storage/radios. In fact powering a display is going to kill overall battery life which is the most important constraint. The display is also the most expensive part of Glass today. So I think the first blockbuster consumer Glass-type product is going to be a bluetooth headset with a camera and no display.
