These days Ubuntu has made some seriously poor decisions; I won't deny that (Unity is a joke, this Amazon thing is a huge lol). But Canonical was vital in the push to get Linux on the desktop and to be accepted as more than a "hacker's playground" that is too hard to use for the average person.

Chromebooks and other low-cost appliances like it are successful in large part because of how easy Ubuntu/Canonical made it to transfer into the Linux world from Windows.

I personally use an Ubuntu 11.x build for everything these days (minus some plain Debian builds on my ARM7 devices), and I really like what they've done for Linux - even if the present stuff they've done has been a little stupid.
