Windows got a lock on the desktop because it was next to f***ing impossible not to buy it every time you bought a PC, and the only alternatives were Dos or throwing out all your computers and software to switch to Macs.
Thank you for proving my point, people obviously liked it, for whatever reason, over alternatives like Dos and Mac.
In what way did the original poster prove your point? I suppose the "Microsoft Tax" is fantasy.
It is not a matter whether people liked or disliked Microsoft Windows it is basically all they get when they purchase a new PC. Basically MS Windows IMHO is "good enough" for people who normally don't know there are alternatives and even if they do, most would not know how to install an alternative OS so they put up with the one that came by default. That does not necessarily mean they like it or hate it for that matter since they normally can't or won't compare against other OS's.
As for DOS you have to be kidding. Ok maybe a MAC, but MAC hardware even though it is now Intel architecture is normally more expensive (although not by much) and has a different GUI to a MS Windows GUI, although from what I can gather MAC users actually do prefer their OS over MS Windows although I will admit they are in minority with regard to PC' sales. Smartphones and tablets are a different matter and these areas are were Apple's OS/GUI and Android's Linux OS/GUI) dominate.
