A little bit of education for you...

Actually, that is NOT true. Open Source companies have PAID developers that develop much of the code. And, at least for Red Hat, ALL of their developers sit in the Open Source side and all development code is released back into the Open Source world (some amazing up-and-coming stuff like oVirt and IPA are two great examples). Novell, Canonical are similar with both of these companies vying for the desktop big time-especially the corporate desktop.

Ubuntu has made the desktop extremely easy, so much so that even though I support and work with RHEL all day, I switched over to Ubuntu for my main desktop (from RHEL 5.2) since once I get my desktop dialed in and the way *I* like it (that's an important concept that Windows users don't get) I don't like to mess with it since I need to be productive on it (as opposed to playing around with stuff), so point and click and a fast install/configuration became important to me at that point.

Novell's work (using PAID developers)  on Mono (the Open Source .Net thing) is also great, and that gets pushed back into the community.

 Now it is a common misconception that Open Source equals free, as in beer. No, it is free as in speech. While it is true that you can download the sources and put together your own enterprise version of Red Hat Linux (got to take out the trademarked items though), for example, you can't however, download (for free) Red Hat Enterprise Linux. Same is true for Novell Suse. These are commercial Open Source distributions that come with, everyone say it together ***support***. The free (as in beer) versions of these phenomenal Operating Environments are Fedora and OpenSuse respectively. Major Fortune 500/100/50/etc companies run mission critical applications on these commercial distributions. That's what I do for a living (in addition to regular Unix [HP-UX and AIX]).

Some companies like CentOS, download the sources (RHEL in this case) and create an identical binary compatible and do give that away for free (as in beer) and accept donations to help cover the cost. Many companies use RHEL in production and CentOS for development environments.

So while it is true that there are those (and it is a great number) who submit code who are hobbyists, retired programmers, or teenagers hacking away in their parents' basements, you diminish the truly great work that professional programmers do by reducing it to just a bunch of  amateurs sharing code.
