I'm getting sick of people complaining that Ubuntu keeps changing things. That's what Ubuntu does! They've done that since the beginning! Oh, they've changed the software manager, oh they've changed desktop environments, oh they changed the theme color... stop complaining and switch to something else.

If you're looking for stability and steadfastness, you probably shouldn't be using a distro with a 6 month major release cycle. Things change, things get broken, and if you don't know that about Ubuntu by now, you're doing it wrong.
