Re: Not heard of Linux then?
Just you wait. MS will be coming out with their Linux (again) and everyone will jump on the bandwagon. The only caveat (picked up from Oracle no doubt) will be the subscription fee for everything.
At least RedHat releases CentOS which is functionally the same as RHEL at zero cost. Although that may change once IBM digests RedHat and throws most of in into the Do Not Recycle bin.
Nothing in this world is truly free apart from the air that we breathe (I hope)
