Arch is great if you don't mind upgrading the entire OS every time you want to install a small utility because otherwise the repositories are out of date and don't have some dependency or other.
:C
Or even if you don't want to install anything because it's all working perfectly well, you still have to upgrade every five seconds to stop the package repo format breaking because it was changed in a backwards incompatible fashion.
Oh and if you don't like the idea of both man pages and the wiki suddenly being unreadable because some upgrade fucked about with fonts files it had no business touching and corrupted things for a subset of users small enough to make it a bloody pain figuring out what actually happened.
But aside from all that, it's great. :T
