If it's a lAser mouse, does it still have a ball to gather the fluff?
Optical ones aren't all they're cracked up to be, either. I lashed out a whole £9.49 last week for a Microsoft Comfort Mouse 6000 (optical, bells and whistles). It didn't work. MS forgot to write a driver for it - the vast MS "Keyboard and Mouse Suite" thinks it's a 4500, which is different and whose driver doesn't work with the 6000.
I found lots of complaints on the web from folks who'd bought them and hit the snag. MS apparently are oblivious to the problem.
A fun hour ensued until I found some helpful person had written some software to solve it. Happy now, and it is a comfortable mouse
