no idea what my mouse is off the top of my head, other than it's logitech as well. but it has a charger and also doesn't need a mouse pad. love it! i've been wanting one that has a charger/cradle for years! my poor hp one i got with my computer 5-6 years ago loved to suck batteries dry.
I love my wireless Magic Mouse from Apple. Got it when it first came out and I've never looked back. It seems to fit my hand better without giving me carpal tunnel syndrome, as my hand is not forced to remain in a cupped position (as with other larger mice).
I'm not picky. Any good solid optical mouse that can stand up to at least 5-6 years of more or less continuous clicking and doesn't mind being smeared with various skin care and cosmetic products, sharpie ink, paint, a variety of adhesives, and during the warmer months, probably a bit of chocolate now and then.
Currently I'm using the Dell one that came with the puter, and over in a drawer somewhere I have a backup Microsoft Plain Old Optical Mouse that I got maybe 10 years ago, and haven't had to bust out yet, knock wood!
