Because of the style of desk I have, a wired mouse is more trouble than it's
worth. The mouse ledge (for lack of a better description) is about 2" lower
than the desk top, with a solid wall behind it. No matter how I route a
cord, it always seems to bind and push the mouse on its own, making the
cursor track on its own. I have a MS Wireless Natural Laser Mouse 6000
(about 4 or 5 years old), and I have had no trouble with it. Battery life is
~6 months with two AA batteries.
I guess I could buy another desk that would be more mouse "tail" friendly,
but this one is just the right height for me, my mouse and keyboard, and my
monitor. Plus it's big enough for my 23" monitor and my 17" laptop to
coexist (and all the other "'crap' that seems to end up on it), so I'd
really hate to give it up to accommodate a wired mouse, IYKWIM
