I did once see a woman in the street carrying a blue iBook. As for things with handles, I've got an old Olivetti luggable with a built-in handle and there is a Smith Corona electric typewriter in a far-flung attic somewhere with a carrying handle.

My most recent aqusition that can be carried in this way is a 1920's wooden lunchbox, the kind that builders and factory workers used to use. You carry it by a couple of brass handles and it probably makes people think "Now that man has LUNCH!"
