Another reason to buy a PowerBook

The new Powerbooks have a nifty Sudden Motion Sensor, which measures not-so-sudden motion too. It reports angular orientation on the two horizontal axes, and g-force in the vertical direction. I bet Make or hackaday will show us how to build this into an all-terrain robot with GPS and lasers and cameras and stuff. No, wait, that's starting to sound like the DARPA Grand Challenge.
