Have just done some tests with an Intellimouse (ball and wired) on a fairly hard, smooth-surfaced, polyurethane foam mat.
About 1 in 10 times, on lifting my hand off the mouse, the cursor moves by 1 or 2 pixels within a second (not always immediately). This simply does not happen with a wireless optical mouse directly on a table top. For CAD work, where many commands require keyboard intervention, this is simply unacceptable; a single pixel error is often sufficient to require correction that often takes twice as long as the original action.
I agree that this would not matter, and would probably not be noticeable, for word processing and the like.
