Mice I've personally tried:
- Cyborg RAT 9:
Little or no software support for Mac OS X. The extra buttons basically don't work. Mad Catz had published some kind of "driver" for the mouse, but for a simple configuration utility it was extremely bloated, slow, and unstable. I couldn't get it working, and the palm rest felt flimsy on my unit so I took it back. Also won't track on a SteelSeries I-2 glass mousepad.
- Razer Mamba:
No OS X support when I bought mine. The thumb buttons foolishly come configured as keyboard keys rather then extra mouse buttons that OS X can actually use. The software for Windows was slow, bloated, and somewhat unstable when I tried it under VMware to configure the mouse. Wouldn't track my SteelSeries I-2 glass mousepad, so I took it back. Too expensive for too little.
- SteelSeries Sensei:
Excellent mouse, awesome built-in hardware configuration. Horrible driver software for OS X, totally bloated and extremely slow (what the **** is with custom user interfaces for a friggin' mouse configuration utility?). If you can deal with that, then the mouse itself is a very nice unit. Probably the best wired mouse I've ever used. Tracks fine on the SS I-2 glass mousepad.
- Logitech Performance MX:
I'm on my third unit in ~5 years now. I keep coming back because they work out of the box with Mac OS X and require zero software to operate all the buttons. The mechanical scroll wheel mechanism is pretty nifty too- you click the centre button and it disengages the scroll wheel click, which lets you fling the wheel in either direction and it coasts to a gentle stop. Great for zooming around in 3D programs and seeking through long documents. I have no complaints about this mouse, other then the fact that it requires a weird USB cable to charge since there is no dock. Tracks fine on every surface I've thrown at it, including glass (!). I think the DarkField sensor is unparalleled in this regard.
- Wacom Intuos 4 Large Tablet:
Uh, it's a tablet. Personally, I hate using it as a mouse, and the mouse that comes with it is a weird piece of crap that feels absolutely wrong in every way. It's a dream to use with the pen for inking, painting, and sculpting applications (ie, Photoshop, Illustrator, ZBrush, Mudbox, etc)- anything that requires pressure sensitivity. For everything else, I've typically got mine shoved to the side and I'll be using my Performance MX on my glass mousepad instead. I've tried several times to get used to the Wacom as a primary means of input but I can never get around how awkward it feels for typical desktop use. IMHO these are specialty tools for specific uses, so I wouldn't consider them suitable for general mouse input.
