This Buzz post by Robert Scoble reminded me of more old stuff done around the same time as the Bluetooth Companion device. This guy would connect to your phone over bluetooth & serve as a push to talk speakerphone, or provide limited calendar/txt access through an App(didnt call them Apps back then, more like a 'Conduit' Service) running on the phone. There was concern with these phone satellite terminal-like devices of cannibalizing phone sales. My argument was that somebody else could always build support for such devices, might as well have been us.
A lot of screen area would have been lost had there actually been a Tag Huer round face watch with an LCD(the analog watch face would have been a screen saver). What I did not know back then was that most folks would stop wearing watches when phones provided the time.
