Go job to them. I know they get a lot of ill will in the Linux community but I've never understood it. They are the only distribution vendor who's managed to make a decent profit from their work. They also contribute a lot to the development of the kernel, gnome and many other projects.<p>I can't say I'm a big fan of using RHEL personally but at work I've usually stuck with them on big servers just cause it's less driver/support hassel and it's easier to find people who can administer them.
