I don't think I'd want a laptop that thin. The thinner something is, the less torsional rigidity it will have, and twisting circuit boards is not good for them. For that kind of money, I'd rather have a panasonic toughbook for my commute. Those things handle rain, snow, 3' drops, you name it. No need for panniers, just bungie the thing to the rear rack and go. If you have someone you can share a tandem with, you can let the other guy be the captain, strap the thing to the back handlebars, and telecommute while being the stoker. Try doing that with some pansy-ass mac!
