KDE yes, but games are important
I considered voting neither, but, while I've never been a fan of gnome, I think games drive the desktop. I've been using KDE for about 5- 6 years. I'm not a gamer, but that has always been one thing I find keeps people on Windows. No games=no Linux for many people. While gaming support won't matter to me I suspect it will lure many new people if Metro is as bad as people seem to think it will be.
