RedHat isn't interested in making a desktop OS, though. Their focus is on the enterprise market, with the Fedora team doing their best to make a desktop OS. It would be very difficult for RedHat or Novell to really make a push into the mainstream desktop market, and I imagine that justifying to their shareholders would be impossible.

The desktop distro teams can't organize enough to get support from major companies, and the enterprise companies can't push into desktop because it's financial suicide to try and support normal desktop users who can barely use Windows.
