I love the new Unibody design on the white MacBooks since October. That rounded edge just seems so cozy and comfortable.
I'll never spend the nutty money I did in 2003 for a 15" or 17" "pro" Apple notebook...such overkill, and I wish I knew then what I know know (because I would've just bought a little 12" iBook G4 and been done with it).
MacBooks are awesome. And especially these recent Unibody models...
