Michael Dell comments working with Ubuntu in a recent interview.

“People are always asking us to support Linux on the desktop, but the question is: 'Which Linux are you talking about?',” Dell asked.
“If we say we like Ubuntu, then people will say we picked the wrong one. If we say we like and support Ubuntu, Novell, Red Hat, and Xandros, then someone would ask us, 'Why don't you support Mandriva? The challenge we have with picking one is that we think we'd disenchant the other distributions' supporters.”
