I don't get this article. Comparing Linux distributions is a old game and debate not worth even having anymore. With LSB and as others have mentioned all programs run exactly the same on all distributions. What's the difference between installing Fedora, Gentoo, Ubuntu or Susu, and customizing it by installing your own dekstop etc? Nothing! All linux distributions are the exact same Linux.
The only difference is the package manager. Thats it. On a server side it makes since to care if you pay for vendor support, but for a dekstop it makes no difference. It boils down to do you like RPM or Debian (or portage in Gentoos case) packages better. Thats all.
The reason the author complains about Ubuntu is because they are driving an improved graphics performance in the desktop. Pioneering new features (enabling desktop effects etc). This is something that people want and is needed if you want to attract people from Mac OS and Windows (Vista/7). If the author had installed the same features on Suse or Fedora, he would have noticed his Intel drivers had problems with those distro's as well...because its Linux, not Ubuntu with the Intel driver problem.
I have used just about every major Linux distribution out there, and a couple years ago I switched to Ubuntu. Ubuntu just works, but mostly its the community. Ubuntu has such an incredible amount of support from a world wide community, it makes it a breeze to accomplish just about any task you may find yourself needing help with.
I wish Linux users would stop worrying about who has the biggest #$@@, and start comparing themselves to something really competitive, like doing things better and faster then Windows or Mac! I am tired of games not running, online streaming content (audio/video) partial working, and the lack of developed software such as beta versions of everthing from Skype to other apps. If you want Linux taken seriously by software developers, why not start unifying efforts to make "Linux" better. Instead of complaining about why some distro isn't as good as another.
