It shouldn’t be though. A command line interface is not user friendly for entry-level users, and until Linux UX designers realise this, Linux will never gain a greater market share. And we have seen this with Ubuntu, Mint, and other “user friendly” distros gaining popularity. I’m not saying that we should necessarily aim for broad-scale adoption of Linux as an end in itself, but more users means more support for Linux which means a better experience for all.
