Query: A great mouse for the mobile trooper!

Initially, I was using a standard Logitech wired optical USB mouse for my HP Compaq Notebook. It worked well enough, but lugging a corded mouse to all my classes, along with multiple textbooks, other computer accessories, and other sundry items was beyond maddening. Then I got the Logitech Cordless Optical Mouse for Notebooks. The shape, though not as good as Logitech's MX510 wired mouse, is excellent, as wireless notebook mice go. I'm not a big fan of those miniscule optical wireless mice not much larger than a real, squealing mouse. They give me hand cramps like you wouldn't believe. Anyway, this mouse is an excellent choice, and the only fault that I can find with it is remembering to switch off the mouse after I use it, but I'm beginning to get used to it, lest I give the battery industry that much more revenue.
