"Converse to number 1, you have the far more consistent releases
of the various Linux distributions. Yes, there have been a few dips
along the way (Fedora 9 being one of them). But for the most part,
the climb for Linux has been steadily upward. Nearly every Linux
distribution has improved with age. And this improvement
isn’t limited to the kernel. Look at how
desktops, end-user software, servers, security, admin tools, etc.,
have all improved over time. Once could easily argue that KDE 4 is
an example of a sharp decrease in improvement. However, if you look
at how quickly KDE 4 has improved from 4.0 to 4.3 you can see
nothing but gains. This holds true with applications and systems
across the board with Linux."
