This is one of the few things that I would change about the MBP? As a user of a 17", It's both my portable and desktop machine. It would be nice to be able to drop it into a slick docking port and not have to reconnect everything when moving to and from my desk. Has apple made notebooks with docking stations in the past or is this something that has always been absent?
TV (or thinner than a macMini) with an 8x superdrive, 4xUSB 2.0, FW400 (800 ?), 5.1/SPDIF audio-out, Dual-Link DVI, GigE, and an IR Sensor for kicks. Put it on an ExpressCard/34 connection over PCI-E and sell it for $199-249.
