A couple of observations as someone who owns an Apple Pro Mouse, BT Mouse and MM.
Now that I've used the MM, the Pro Mouse feels heavy. Rock solid feel, but at the same time feels like it takes a lot more energy to move compared to the MM.
The BT Mouse is not instantanious like a wired one. Bugs me sometimes. When I do presentations, it comes in very handy as a remote control. I can use in my pocket or on my leg.
The MM is cool. But at times feels cheap since it is lighter than the others.
As for looks, I like the Pro Mouse the best. I have a black one.
I do like the MM's scroll button/wheel. Having both H and V at one time with one control is very very handy. Sometimes I wish the ball were a little bigger -- maybe something about 70-80% bigger radius than the current scroll ball.
Right now, until I get to use the MM with Tiger, I would rate them like this:
- Pro
- MM
- BT
Over the years, I've used quite a few different mice. As for wired verses BT, I prefer wired most of the time. No need to worry about the batteries, they have instant response, and they usually feel more accurate in placement/movement.
