New gadgets — I mean whole new gadget categories — don’t come along very often. The iPhone was one recent example. You could argue that the iPad was another. But if there’s anything at all as different and bold on the horizon, surely it’s Google Glass.
That, of course, is Google’s prototype of a device you wear on your face. Google doesn’t like the term “glasses,” because there aren’t any lenses. (The Glass team, part of Google’s experimental labs, also doesn’t like terms like “augmented reality” or “wearable computer,” which both have certain baggage.)
