I've just recently started using a Mac after decades (shudder) of using Windows, and one of the things that has been driving me crazy is the way the mouse moves. Over the years I've used lots of different Windows mouse drivers, some of which included an acceleration function. In fact, I believe mouse acceleration is built right into Windows XP, though it's easy to turn off.
On the surface, mouse acceleration is a good idea. It allows you to travel across a relatively large amount of screen real-estate with your mouse with a relatively small (but quick) flick of the wrist, while still giving you a high level of accuracy when moving the mouse slowly.
My problem is that in OS X (Tiger) the acceleration is set by default to be fairly aggressive, and there's no way to turn it off. As if feeling like I don't know my way around a new operating system isn't bad enough, this default mouse behavior makes me feel like a complete newbie.
I googled around a bit, and at first it looked like the only solution would be to purchase a 3rd party set of mouse drivers. However, there is a free solution, but it's not going to sit well with you Apple / Mac purists. If you download Microsoft's Intellimouse drivers for Mac OS X, you can have the choice of using OS X's default mouse behavior, or using the Intellimouse settings, which severely cut back on the acceleration levels. You still get the advantage of increased accuracy at slow mouse speeds, but for the way I typically use a mouse, I'm able to be quick and accurate again, and I can stop worrying about where the speed barrier is that is going to launch my mouse pointer off into next week.
This is one of those tips that is probably only going to appeal to the new "switchers" out there like me, or maybe those that work on both Windows and Mac machines, and want more uniformity with respect to their mouse movement. But I tell ya, this simple mouse driver makes using a Mac infinitely more pleasant for me.
Oh, by the way... in true Microsoft style, installing this mouse driver requires a reboot. Who knows, maybe that's actually OS X's fault, but it seemed a tad ironic to me.
