Just received my Z3 and I realized that I'm using a desk that's primarily metal (SecretLab Magnus). The top of the desk is intended to be a mouse-friendly surface, but the Z3's bottom magnets are understandably causing an awful lot of drag.

I'm sure I can just grab a mouse pad to introduce some distance between the mouse and the desk surface, but does anyone have any other clever ideas that could mitigate this problem?
