I hated it
I despised it.
I refused to use it.
I've been using KDE then Gnome for years, and been quite happy, Unity sucked.
When I installed a new Gnome system, I'd install enough kde libs to get konsole going. I had a bunch of stuff like that.
Then my primary computer died.
And the backup system was the test Unity system.
Fuck it.
I got all my production stuff going, made sure my files were ok, and then sat down and slowly, carefully, read the Unity docs. And tried stuff.
And found out I really like it.
I simply never gave it a try. I tried to work my default way that I had evolved in the previous ones. They were rip-offs of Win95, so it was all comfortable.
Unity is different.
