I have a Microsoft 4000 wireless mouse on my Dell at the moment and it works great. As I am about to switch platforms and buy a new iMac, I was wondering if I should try the Mightymouse wireless. For $50 I can get Apple's wireless keyboard and mouse, which is a pretty good price. Is the Mightymouse a good mouse? Does the wireless have good range? Good battery life? Oh, and since I'm one of the "switchers" I *will* need to right click.
