Mouse problems

I tink it's OSX related from the threads I have read here. Using Windows in Parallels would probably fix it.

I'd buy a Magic Mouse.

I can't speak for Logitech mice directly, but nearly every mouse should "just work" without any drivers in OS X -- as far as basic movement, two buttons and scrolling is concerned.

If you want more functions than that -- 12-buttons, user-configurable options, etc, etc, then you're probably going to have to install some third-party drivers, and these can often be quite poor.

However, some Windows switchers do claim that there is a major issue with the way the pointer moves in OS X (lag? acceleration?) -- though many OS X users are oblivious to it. I've never noticed any trouble with it, though I've been using Macs for twenty years. But I don't think that's what you are describing, as you are getting different results with different mice.

Have you installed any drivers? Try uninstalling them, or making sure they are up-to-date.

Have you tried the Apple Magic TrackPad? I much prefer it to any mouse, and it's clear that OS X is moving more towards that kind of touch-sensitive panel as an input device, e.g. gestures and all. I generally recommend it as a much better way to control input than a mouse.
