I'm looking for a corded mouse to replace my cordless Logitech MX Revolution. I'd like something similar, but corded, and with OS X native drivers so I don't have to use steermouse/usboverdrive/etc. I like having the side buttons assignable, if that can be done with an OS X native driver. If not, I could still use steermouse, but I'd rather not. Any suggestions? I've had the mighty mouse (yuck), Razer Pro Click which was decent, and the MX Revolution.
