What's next in Red Hat Enterprise Linux (part 2) (Red Hat Magazine)

I haven't heard of this "Ubuntu" thing you mentioned.  What is it?

But seriously, the difference here is the "Enterprise" part.  If you want to compare Fedora
and Ubuntu, fine.  They are pretty much neck and neck with regards to feature set.

Many of those features are fairly new and at a questionable level of stability and
robustness... so you don't want them in an "Enterprise" distribution just yet... but since
RHEL 6 is some time away... perhaps all of that stuff will have been improved upon enough.
With Red Hat bumping them up to "Enterprise", they surely will get a lot more testing and
coding that Ubuntu (and everyone else) can benefit from.  The difference is that most/much of
Red Hat's work (and Fedora's too) makes it upstream.
