It's not for the average user per se. And like all distros, there one for everyone. Arch is for users who want to use their computers, not their OS, if that makes sense. Like me, they prefer their OS to be as less intrusive as possible. It was the main complaint I had about windows. I want my OS to not obstruct my productivity with woo hoo pretty colors and designs, and fifty thousand services I have to turn off because I have no need for them.
