Have you heard of the inPulse Smartwatch? If not, you should probably check it out. It's a nifty little gadget that can connect to your Android (or Blackberry, but who uses those?) via Bluetooth, and show you text messages, email, calendar appointments, caller ID info, and more - all on your wrist.
That's not all though - this thing has its own apps, too (and some pretty rad options, might I add).
