Professional isn't so Professional

I was sitting in a Vertebrate Biology class the other day, and the teacher was using a Compaq running Windows 2k Pro. The thing crashed 3 times during the one hour class. All three times it refused to boot up all the way, and crashed during the Windows loading screen. He eventually gave up trying and just shut off the projector. Makes you wonder why people still use Windows... The PowerBook could have done it flawlessly. :)
