UW smart watch

Though it may be lost on creatures of intense, unwavering habit like us, one can definitely see why the University of Washington-built "smart-watch" (no, it's not a SPOT, though it probably should be) would be such a useful tool, being that it warns its user that they're forgetting their wallet and keys (or whatever else). It's pretty simple in that it uses RFID to keep track of what you've got with you, but things get kind of ugly with the concept and prototype once they they add a "pocket server" you have to carry around to make the whole thing work. But RFID is still in its infancy, so we'll try and keep that in context.
