I'm trying to find out all my options for a bluetooth mouse. What I prefer is 2 buttons + scrollwheel in a relatively normal mouse shape. For reference, the Logitech MX-300 has what I consider a relatively normal shape, so is the Apple bluetooth mouse, except of course it is only one button. So, besides the one button Apple one and the Microsoft one that is a funky shape, what else is about for bluetooth mice? And of course, this has to work with the internal bluetooth adapters in the Powerbooks and Powermacs.
