According to this article, the Linux desktop market is too tough for commercial options from both Novell and Red Hat. OpenSUSE and Fedora are free options still available for the desktop from both companies. They cited their largest competitor (and frenemy for Novell) Microsoft, as the main reason that selling boxed versions of their desktop software is rather ineffective.
What does this mean?
It means that desktop Linux will be ruled by free distributions, and not those that you buy at the store for $60+. Why buy something when you can get it for free? Distributions such as Ubuntu and Fedora will be the market leaders in Linux desktop catagory.
