Does anyone have any updates on Bluetooth mice for OS X? (Besides Apple's mouse...) Coming from the PC world, I am partial to mice with 2 (or more) buttons, and a scroll-wheel. I (foolishly, in hindsight...maybe my screen name should be Epimetheus) bought the Logitech MX900, in the hope they would provide OS X drivers. I gave up a few months ago, and just went with Microsoft's USB RF mouse. But I would really like to cut the USB cord. Has anyone bought RadTech's Bluetooth mouse?
