Pebble: E-Paper Watch for iPhone and Android by Pebble Technology — Kickstarter

Most successful KickStarter project ever! $4 million pledged toward a $100,000 goal. And the money keeps coming in! (The pledge went up by about $1000 since I started typing this message)

Fantastic idea. There have been similar ideas before, but they all used an LCD or OLED display. Who wants a watch that you have to charge practically every single day?? E-ink (or e-paper) is such an obvious solution, makes you wonder why it wasn't thought of sooner.
