It's not a mess. If you install an appropriate distro, say Ubuntu or Linux Mint, the average user would be just fine using it. Judging it based on installing it is being disingenuous. The average user isn't installing an operating system, Windows or Linux. You know OS installation gets handled by someone that knows what they are doing regardless of what OS it is.

The problem I have with his "challenge" is the same problem I have with all so called Linux challenge type videos. The average user is not installing an OS, any OS, period. Judging Linux by how an average user can or cannot install it is disingenuous and stupid. It should be judged on how usable it is by the average user if it's already installed and setup because that would be how it's used. It would be installed by someone that knows what they are doing just like they do with Windows.
