A stable, (usually) freeware, operating system, limited in usefulness to most users. Good for running servers snd business machines but has major inherent flaws that prohibit it form ever becoming a truly mainstream OS for personal use. Its just too bulky and user-unfriendly to ever gain the popular eye.
Linux is a cool idea, but since its a pain to install and operate, and incompatible with nearly all software on the market, itll never get far beyond the geeks and zealots.
Contrary to what is claimed by many Windows-haters, not all versions of Linux are particularly good. The price you pay a stable OS is the amount of fuss and bother you undergo in trying to find a decent version of it!
I installed the free version of Linux that came with the book "Linux for Dummies". It didn't work. I am still trying to work out if there is any irony in the preceding two sentences.
