Phone vs watch
I gather that increasing numbers of people these days use their cell phone to tell the time, and don’t bother with a watch.
However, the watch is fighting back. Behold, the quad band GSM phone in a wristwatch, with Bluetooth (so you can pair it with a headset for phone use) and OLED display showing analog hands. Plus 1.3MP camera, kinetic battery recharge, and MP3 player.
At 13mm thick it’s still pretty bulky, but not much worse than my Casio G-Shock.
