John Gruber over at Daring Fireball published probably the most in-depth review of a piece of hardware I've ever read. He recently got a 15" Powerbook and this is the result as he covers everything starting from the appearance, the keyboard, RAM, the display, etc. But that's not all, Gruber gets into the fact that Apple will release Intel-based Powerbooks in 2006 and gives a few points on why it's good to wait for them or not. If this doesn't get your mind cleared up about wether a Powerbook is a good choice than nothing will.
