Just switched from pc to a beautiful 24" iMac and I love it. Now I want an Apple notebook. Macbook would be fine for me but when should I expect a MAJOR update, not the small one like a while back. I want to get it for my wife as a christmas present. Do you think they will come out by then? I think it will be aluminum according to Jobs wanting everything aluminum from now on. Or do you think Mac World 08'?
