I apologize. I was only responding (in a half-joking manner) to your own misleading statements. If you do some reading, you'll find that many people have problems with Ubuntu's updates. Many users don't even attempt to update before doing a full reinstall.
And I wasn't talking about servers or supercomputers. Ubuntu is a desktop distribution. Desktops have a lot of crap that servers don't: X, gnome/kde/etc, compiz, sound, wifi... It's most of these things that cause instability, not the kernel itself.
The other statements were fully joking. It was a page right out of the Linux Youth Handbook. Many Linux zealots bash Windows despite being completely ignorant about it. "Windows 7 needs to be reinstalled every 6 months and blue screens twice per day and still uses FAT16 which needs to be defragmented ever time you write a file and gets owned within 90 seconds of connecting to the internet even with a firewall!"
