Mouse with a frickin' laser on its head
This is just too cool: the latest Microsoft mouse has been released, and it's amazing. Not only does it use BlueTooth, but it has buttons for controlling PowerPoint, so you can walk around the room giving your stirring speech whilst casually moving from page to page. (Make sure to use Live Search on "Edward Tuffte and PowerPoint", by the way to help you determine the difference between "stirring" and "boring to the point of being fatal").
Best of all: it has a built in laser for blinding hecklers. Er.. I mean, for pointing out interesting things on your slides. I'm so getting one of these, and then maybe I'll be motivated to put interesting things in my slides.
