Actully there are not. I just got a powerbook and am a Pc switcher. There are somethings in life i cannot live without, a good mouse should be one of them, why mouse makers cant made the mouse i, and im sure, every other powerbook/ibook user wants is beyond me.
What Im looking for:
*Bluetooth with no dongle
*on/off switch so i can cary it in a bag and it does lose power
*a decent size, seriously, who uses the small mice?
*left/right/scroll and the back button, that is all i ask, i want a back button
*no base station, be able to work with the mac directly
*Good Battery life, rechargeble is fine just no base station.
There are really only the "the Mouse" which as you said is cheesy, the Radtech which is ugly and small and no back button, logitech is out cause of the base station (which is too bad cause they are the best), Microsoft is too sturborn to build a good mac mouse, Kenningtons is nice but too few buttons but is probably the closest. If i am missing one that actully is good and meets my criteria PLEASE tell me, I would buy it in a heart beat, no matter the cost.
