Are you serious...?
All the *nix fanbois out there, do you really mean it? If so, wow..
I have to say, I don't LIKE Windows as such, in fact it's a pretty poor excuse for a cutting-edge OS (and I'm talking about XP - my current install has lasted me about four years, through two complete hardware changes). Sure, it's starting to get slow and has inexplicable bugs, but at least I can fix most of them. On top of that, I can play games. And if I would be an ordinary user, I would surely appreciate how relatively easy it is to use/install/etc. Of course a lot of this is so because M$ have people firmly by the b@lls, there's no denying that.
I tried Ubuntu 7.10 recently, and it just didn't satisfy me. Sure, it was free, it did things well, the package manager actually works, and there's plenty of free software for it - but I still can't play my games on it, and it won't recognise some of my more "special" hardware unless I'm willing to really get my hands dirty (which I am, but I'm not a "normal" user).
So honestly, please stop trying to shove *nix (or even MacOS) down people's throats when they're still not suitable for a large chunk of the audience. I'm sure they'll get there, it'll just take a wee bit longer - say, maybe until mid-2009?
