does the M stand for mouse
If you have a PS/2 port on your PC still, this is seriously my all time favourite mouse: http://www.flickr.com/photos/9528724@N03/sets/72157624432533156/It's biggest flaw is that the shafts are plastic. If it had steel machined parts it would be true .Break it in and after a day or two it spins really fast. You can even convert it back to a regular mouse, but man frick all of that I need to live my life like I'm playing centipede in the arcades.There's a guy who sells these on ebay NOS in the box for $5
my roommates got an original model m, it makes great click noises.
big rigs is great and i want to suck his cock
