About Linux, I feel Con Kolivas, a former Linux kernel dev said is very accurate. There could be a bug in the kernel that causes desktop use case go to a crawl or freeze can be ignored for years, but Oracle reports there is a bug in the server usecase that causes a 0.5% of performance lost once per month and the same day it will be fixed.

Enterprise use simply eclipse the focus of the devs to regular people use. Which just only highlights even more why the desktop experience improved so rapidly when Valve decided they wanted Linux for gaming. Simply there wasn't anyone that cared for the end user experience and wasn't running their own fork (yes, I am talking about Google).
