I could moderate you down, but that wouldn't be fair. Instead I'll just comment and say I disagree with you. As a person who has been using Linux on his desktop for over 7 years now, I'm more familiar with that than the gazillion flavors of Windows (7) nowadays. At least I know that everybody agrees that Vista is terrible, but I wouldn't know the difference between Starter, Premium, Professional, Enterprise or Ultimate. In my opinion that's based on nil experience with any of these flavors, I think that's more confusing to people than a Linux distro flavor. I always say to new Linux users "give Ubuntu a try" and to the techies who want to experiment with brand-new software I tell them to try Fedora.
And what you call disagreement among users/developers, I call variety. Don't like Ubuntu? Fine, give Fedora a try, or OpenSUSE or Debian. It's all good, it's all free and you (listen carefully now) can decide without spending money. I know really experienced Linux users who are so accustomed to using Debian, they can customize the entire system to look exactly the way they want to. Same goes for Ubuntu people and Fedora users. Don't stick with one distribution, try a lot of them, until you find one that you like. And even then, you aren't forced to stick with it. And even if you pick one that I can't 'support', I can tell you where you can go find help. Lots of fora and IRC chans filled with experienced people who can (and most often will) help you out.
Linux _is_ simple to use. Depending on the distro and your personal preferences. I can make myself comfortable with Fedora and its gnome shell, but I'll probably have a slightly more difficult time trying to get used to Ubuntu's Unity. But that's just me. I'm glad other distributions exist that offer different things. Freedom to use any (or none) of them. Gotta love it.
