If you have an account (and stay logged in) you can get some of the benefits described in the article with an alternative skin (collapsed menu, limited line width, maybe a better font). Check out the options in the Appearance section of your user preferences.

I like MinervaNeue (sample page here: https://en.wikipedia.org/wiki/History_of_Anglo-Saxon_England...)

Wait, that's the Wikipedia Mobile layout, except with a lot more desktop functionality (and changes such as Talk Pages not being collapsed). They had this lying around the whole time?

If you don't like being logged in, it's worth noting that's also the default interface for en.m.wikipedia.org (the mobile site, which is perfectly usable on the desktop)
