iPhone killer at Starbucks !

You'd be recharging your watch every day or two. Random off the top of my head guesstimate is that a bluetooth radio is probably something like 1000x more power-hungry than a digital watch. Those things go for years on one tiny battery.

How about one of those old-fashioned pager chains? Ugly as heck, but it never needs to be recharged!

I'm gonna walk around talking into my iPod Touch and see who realizes that something's not quite right.
