Will people ever accept wearable computer glasses? Maybe, if they look like normal glasses and the gestures required to control them are not ridiculous. It's clear that we want mobile connectivity, but we also want more power, bigger screens and greater convenience. You can't really have bigger screens as well as convenience unless the screens get much closer to your eyes, so glasses are the way forward. The problem is that glasses don't allow the same kind of touch gestures we are using on our phones and tablets, nor the classic keyboard and mouse of a desktop system. It needs something new, and preferably something that doesn't look like we're talking to ourselves while poking at invisible fairies. That's tricky, and I don't think anyone has yet made anything truly intuitive and graceful for a wearable computer input system.

PS - Google recently put up a concept video of a glasses-based system.
PPS - And they've built some of them, but I don't know if they work as well as that.
