With my Apple wireless keyboard and Magic Trackpad, what I'd really like is a lap desk that is designed to accommodate them clipped together. I envision something like a thin but rigid plastic slab with flexible spring "clips" along the top edge which would clip on to the round back part of the trackpad and keyboard, and they'd be spaced such that you could have either device on the left or right.

(The rigid base is necessary so that the trackpad has something to click against.)
