no need for either
Just thought I would add my opinion. The MS days of controlling everything are over, even the Linux admins are done for (in my opinion)
Imagine an office, each PC runs an O/S, they connect via a router to the internet (all secure) , and they use Google Docs for their workload and email. Google docs complies to many security standards - which RHEL and MS could only dream of.
Technology has moved away from Admins, support people, it's now available in the cloud and automated.
