Look at the roadmaps of each major distribution to determine whether the features, support and pricing will pay off for your infrastructure and workloads.
Linux OSes also target coexistence with Windows, as many data centers are adding Linux servers to all-Windows shops. For new Linux administrators, there are some universal lessons that will ease the transition.
