Well, when you consider all the stuff on those 2 cd's, yep.
2 cd's of redhat (or any linux for that matter) is probably enough software to run the equivilent of Win2000 pro, server, and advanced server (in capability, not stability..

this is much more stable) Plus there's quite a few space eating window managers...
And then there are some things that you probably would have to buy much extra software to do.
I'm sure there's a few exceptions, but you get the point.
