Hrm, seems like it would be rather useful to pick up an iMac Mini as a mobile desktop. Similar to the Cappuccino mobile PC that never took off.
At 6.5" x 2", it would be simple to toss this into a bag, go to work, plop it on the desk and perhaps into some kind of "dock connector" like they make for the iBook. Either that, or just plug in your monitor & power and use BT mouse & keyboard. Then pick it up and haul (term used lightly) home. A cheap desktop replacement.
