Wow, talk about shifting the goalposts. This started as a discussion of who would game on Linux, and why would they do so. I gave you a bunch of reasons, and rather than respond to them you decided to turn it into a "Linux on the desktop" debate, and what is best for "normal users" and "average people".
I'm not talking about average people, because I couldn't care less what they do on their computers, what operating system they run, or what software they use or what games they play. They can do whatever they want on their computers - they're their computers. The only reason I would like to see more Linux adoption is so that I see more native Linux software.
And there's not even very much software I want: a good, easy video editor, and FL studio (or a replacement for it) are the only 2 that spring to mind that aren't games. Games are the big one. And I'm prefectly happy to not play a game because there's no linux port - there is no game that I'm so interested in to make it worth the hassle of installing, much less using, windows.
One of the reasons there's not very much non-game nonfree software for linux is that they have a hard time competing with the huge library of free stuff which is available - why would I buy sound forge when I can just use audacity? There are only a few niches where there's any chance for a nonfree option to get a foothold. And in many of those cases (e.g your tax software), any linux user can just run it in a VM or using wine, which incidentally is a better desktop experience than using a native windows install, for reasons I've already related and you've already chosen to ignore.
I'm not here to debate what "average people" want or care about, or when the year of the linux desktop is coming, because I really truly don't care one whit. I don't care if you and 99.99999% of the ignorant masses like your terrible interfaces (which you've already admitted you don't, but you're apparently happy to be spoon-fed crap and praise the people who feed it to you). For me, the year of the linux desktop was 2001.
