I am very grateful for this cleaning technique. I shall try it tomorrow, though I have no idea where I will find access to an air compressor. My dad's is 200 miles away in another country.

As far as the Mighty Mouse's lousy design, it is a hell of a lot easier on my wrist than the otherwise brilliant Magic Trackpad (multi-touch is the greatest thing since sliced bread, but having to hold my fingers up off the pad for hours hurts like a railroad spike driven through the wrist). Can anyone advise as to the usability of the Magic _Mouse_ in this regard? I'm hardly about to speculatively drop $70 on something that may offer no net improvement.
