This is anecdotal, but a trend I am hearing from companies in the cloud hosting sector is that because Ubuntu has been a stronger desktop OS (better at "just works" out of the box, particularly on laptops), developers who use it for their desktop then choose to use it instead of RHEL for servers when they are deploying in their enterprise jobs (use what you know). The result is a rapidly growing usage of Ubuntu for enterprise servers. RHEL is still dominant, but the usage of Ubuntu is significant and continuing to grow quickly.
