I'm interested to see the results of this, too. The idea that a watch needs to be charged daily (or nearly daily) is utterly ridiculous. Like my Palm Pilot 500 which can run for weeks or months on a pair of AAA batteries, I'd rather have something simple that requires little effort than something with a thousand features which requires constant attention, software updates and charging.
The only watch I currently own is a Casio G-Shock which syncs time via WWVB and keeps the battery charged via solar. The battery still needs to be replaced every seven years or so, though. Once I can replace the battery with a supercapacitor, I'd never have to open the watch for any reason, and I'd be happy.
There should be more computing which focuses on doing certain things exceedingly well instead of trying to do everything.
