Kickstarter has some great projects lately. Now you can find the Pebble, an e-paper based watch for the iPhone and Android. You can connect the Pebble to you iPhone or Android, upload apps and use it as an extention to your phone via Bluetooth. Imagine, you are being called and you see the name of the caller on your watch. Or you are playing music with your iPhone and use you watch to skip to the next track. This is only a very minor selection of the possibilities.
