Ubuntu is dead for me since the release where they were sending the data you typed in the internal search across the internet. And Shuttleworth claimed it's not a big deal.

Since then, I'm a happy Linux Mint user.

And since we are talking about Linux distros: I tried a bunch of times to live with a distro that has no start bar at the bottom. Even after a few weeks my productivity does not recover. It's a mistery to me how you can live without it. I happily stick with the Mate desktop which has it.
