One way or the other - it does not matter. I would not be even surprised if Linus used Windows. I would not be even surprised if he is disgusted with the current Linux the way it is... Linux went over to the dark side, to follow Windows with loads of senseless bloat and inefficiency. There are hundreds of distros and none good (Well, maybe except TinyCore...).
Multitude of Linux Distros are created and they die. Those which survive thanks to their large development base are often the worst examples of bad quality - See bmarkus on Mandriva...
Lack of centralized management and control is probably responsible for this fragmented landscape of Linux, which means Linux is not able to compete on the desktop side.
Instead of senseless wasting programming skills to create hundreds of poor quality distros, a unified strategy should be in place to create one Linux system that is high quality and can truly compete, putting all that wasted programming effort in one place, for one single purpose. Had this happened, Windows would be history...
