What "great" features? Buggy and slow interface? Inferior terminal and UNIX support? Lack of customizability?
I don't like multiple key presses for what should be one simple key press it seems sloppy and counter intuitive for a key that's existed for decades.
Furthermore, you sound like you're describing Linux itself. You're either a troll or terrible at indicating sarcasm.
The next issue I had was the lack of a nice, Apple-supported package manager. Homebrew and ports are poor replacements for things like Pacman and the AUR. There's no emphasis on many of the things that makes life on Linux easy.
These are my top two complaints; the second can be debated, but the first is unjustifiable when Linux runs on the same hardware without hiccups.
