The Trios II allows you to have up to 3 operating systems on one machine and switch between them with the push of a button. I had heard about the original Trios some time ago and thought, "Sounds cool. Probably doesn't work." Then the Trios II came out and I began hearing good things about it from people I knew and trusted. Since my foray into the Linux world, the first and most popular question I get is, "How do I dual boot with Windows?" My answer was always, if you have to ask, don't do it. Why? Because I've seen even alpha-geeks hose their machine dual booting.
