The last part of your comment seems quite absurd. Simply put, just because you may not know of anyone in your immediate professional or social circles using RHEL, does not mean it's not extremely popular in the capital E enterprise. AFAICT, RHEL is the Linux distribution of choice in most enterprise IT organizations /because/ of it's commitment to long-term support, stability, ABI compatibility, programs like EUS, and so forth--the list goes on.
