Linux is too user-unfriendly. It's probably a gem when you get to know it (after about a decade or so), but I'd rather use a system with integral GUIs and meaningfully-named files (i.e. not mkdir, cat, ls, mv, etc.).
I already made this choice in my mind years ago: Windows sucks, Linux sucks, don't like Macs, don't know BeOS, QNX has no software...oh well, I'll stick to AOS and MOS.
