Mark posted "news" over the weekend: Ubuntu (Canonical) is not negotiating a patent license with Microsoft. Well, of course not, Mark: no one ever accused you of being lame.
Seriously, Ubuntu is not in the same league with the other s that have capitulated to the Microsoft FUD machine. Ubuntu is on a serious upswing, not downward spiral. Why negotiate for phantom benefits unless that's all you can hope to achieve?
All that said, Mark isn't writing off collaboration with Microsoft (or anyone else) forever. He just doesn't feel that this particular kind of "collaboration" makes sense.

This  is a video I made that just shows off some of the cool features of Ubuntu.
