here is a great idea for smart phones, that should have been realized 5 years ago. People don't use wristwatches anymore because they use the smart phones, right? But you have to turn the phone on every time - a two step procedure to tell the time. Designers, give us an always-on watch on every phone! The Pebble is kinda right idea, but it's yet another gadget to carry (and it does not exist!). Just dedicate 1 sq inch of the screen for the time and leave it on all the time. Or an LCD screen in the upper right corner, synched with the phone ($5 solution). Or something better.
I've read about the Sony "Android watch". It's nothing more than a "dumb terminal" that communicates with your Android phone via bluetooth. Break that bluetooth connection and... poof... Nothing more than a small OLED device on your risk flashing error status symbols.
