I was reading your entry about the 900. I'm really keen on using this bluetooth baby for my Mac as I'd like to have the back/forward buttons on a bluetooth mouse (haven't been able to find a bluetooth mouse with build in back/forward buttons for the Mac yet).
I know that you mentioned that the 900 has no Mac software, but have you tried installing the Logitech MX 700 Mac software. I have a feeling that this might work as the 700 looks exactly the same as the 900; it seems the only difference is that the 700 doesn't have bluetooth.
The download is available at:

Tell me how it goes.
See you,
David
