*Wrist-top form factor. Yeah, they've tried it before, but this time it's not the old-school Dick Tracy watch, it's a stripped-down micro-Android.
*One's immediate reaction is skepticism, but that's what people were saying about pads and tablets not so long ago. There's an Alan Kay school of thought in ubicomp that says it's the destiny of computation to shrink and scatter until it vanishes into walls and clothing. In which case, if I want to know what time it is, I just look at my wrist. Not at my watch – at my wrist. Glowing time numerals get laser-beamed onto my wrist via millimeter-scale AR.
*In the meantime, though, one wonders how dinky a display screen can get and still be commercially viable. Watch-face sized? Postage stamp? Flea-sized? Maybe just the itsy-bitsy blinky-light of a ThingM LED, the "atomic unit of ubiquitous computation"?
