Ah, the Mighty Mouse. While some of us here at Giz think it sucks, others swear by it. Well, good news for the latter, because the Mighty Mouse is about to get a Bluetooth wireless upgrade. Documents on the FCC site show that the mouse is going to look like the old version, except for the bottom that you remove to replace the rechargeable AA batteries.
However, unless Apple has addressed the problems that current users like John have encountered—busted scroll ball, right/left click confusion—new users may want to stay away.
