I've seen a lot of posts comparing the size of the new 16.2" MacBook Pro to the old 17" Powerbook G4 1.67 Ghz. Here are a few photos for context to show you the size difference. Also, check out the sheer quantity of ports on that 17". I'm counts DVI, S-Video, Ethernet, Firewire 800, Firewire 400, 2xUSB 2.0, Modem, Headphone Jack, Audio In, PCMCIA card slot, charger port, Kensington lock, Superdrive (does that count as a port?!?).
