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.
