Ordinary users are mouthbreating idiots. Have you not read BOFH?
But seriously. When Windows pisses me off with its own labrynthine absurdities, its DLL hells, its craptastic insistence on some specific library or .Net version, its poor 64 bit support, or its inability to get at what is wrong to fix it, I don't get pissed at all the windows people who behave like zealots and call me TDO. Windows 7 and 8 are the VERY FIRST that have run stable for me, and by stable I mean not BSODing after any length of uptime. XP was marginally tolerable once I spent days tweaking registry entries. I have had to twiddle every operating system I've used in some way or another. The difference is I recognize that all operating systems suck, its just where they suck and what bull**** you have to do to get them running right.
Don't even get me started on that pile of crap known as AmigaOS.
