Heh, I have the reverse problem, on Windows 7 my uptime is measured in months and everything is great. On Mac everything, including drivers for the Mac's very own mouse and the built-in microphone, we atrocious.
Heck, for my first old 4Gb RAM Mac I installed this piece of software from app store that would consume all the memory on the system over a short time to force Mac to actually manage memory and prevent other apps from stuttering and OOMing when the memory was supposedly low (it really wasn't, as this app's overload-free-memory routine showed). It even had a paid version that would do the memory-overload automatically when memory was low. That is the most Mac thing I've ever seen :)
