I never got used to the OS X mouse curve either. The mouse acceleration on the Mac has always been a bit leaden at low speeds, and too fast at higher speeds, even with Mac OS. It's odd, because the trackpad acceleration is very well done. The best solution I've found is to buy a Microsoft mouse. As with most Microsoft hardware, they're good value. You can then use the supplied Intellipoint for Mac OS X software, which, along with a bunch of pointless junk, lets you activate a Windows-style acceleration curve. It might sound daft, but this utterly transformed my experience of OS X.
