The lack of a security slot to cable down the airbook is drving me nuts. I like to putter around in my local coffee house and leave my mb pro cabled to the table when I go to the head or wander off in a fog. I'm thinking of inventing my own security system -- or maybe having a machine shop drill a hole. or calling Steve and asking him why he created this problem in the first place. Any way it's kept me from buying the mba till now. But I'm about to spring for it knowing full well that a week later they'll announce the next iteration. Any thoughts?
