I have a Logitech VX Revolution that I love, but my new Macbook Pro has only two USB ports and having one of them taken up by my mouses wireless adapter is annoying. I haven't seen a single nice bluetooth mouse either. The main reason I love my Logitech mouse is because it's ergonomic. I would go for the Mighty Mouse but given all the problems I hear and that it's not shaped ergonomically I'm hoping Apple releases a new and improved mouse that doesn't have the trackball problem and that is ergonomic. If not I'm crossing my fingers that Logitech releases a VX Revolution that works on bluetooth.
