Ubuntu - Canonical in general - is not a good representative of "Open Source". They don't contribute back to Debian, don't cooperate with the Gnome project (Unity?), and there are other options out there. They are good at marketing, though. Ubuntu feels like a wonky OSX clone..

What really annoys me is that they have made people in general think of Linux as "Ubuntu". There are other options. :)

I am a happy Debian KDE/lxQt user not using *untu. :)
