My dad use a logitech cordless and the battery doesn't last long at all. Maybe it would be better with a set of quality rc batteries, but if you add all the cost up it doesn't worth it (mouse+battery+charger). I don't like cordless, have no cable drag problem so see no use getting one for myself.
I got my eyes on the logitech dual opt. with cord, sweet looking toy with a thumb button to piss you off hitting it by accident. I like it a lot.
Got my first optical mouse because the logitech gaming mouse I used died (too much shooting and switch inside died), but I had enough of cleaning the wheels and the ball all the time. The optical slide better on my desk (no ball = less friction), doesn't need a mousepad at all. But I still have to clean the rubber feet once a while, it picks up everything and after a while stop sliding well.
If I could find somebody who can cut two small bearing balls in half, I wouldn't have any cleaning problem anymore, also it would slide like crazy. (now watch some company coming out with a mouse using bearing balls for feet instead of the plastic pads)
