I like the simplicity of a one-button mouse, actually (I like the Pro Mouse-which I've said before.) especially on the iBook. I think it adds to the design, which in itself works because it's so simple. One of my biggest complaints with pc notebooks is that they cram so much junk in their machines, like all these ports all over the place. Then when you fire up XP you're accosted with 10,000,000,000 icons all trying to get you to sign up for an online service, or 50,000 different online card services.
