Its cool, but sold with a death penalty. A mice with resolution high enough to move past a 1940x1440 screen on only 3 inches does not make up for the "you need to change batteries once in awhile" drawback that I see as a much more important issue than cord-or-not. If it wasnt wireless, I would had grabbed one. Best Regards JemyM

That's why you need a Logitech MX700. Thing tracks faster than corded MS mice and the receiver also is the charger so you don't have to change batteries. ;)
