Much of this article is simply "I don't know Linux" and basically in no way reflects the Raspberry Pi itself. Clearly, the author doesn't know much about the ecosystem either; they suggest running a cheap intel machine because then you can run Windows... even though you can run Windows on a Raspberry Pi as well [1]. Not that I don't disagree with their general end sentiment, that you can often get a whole lot more, for relatively little extra cost.
The author seemed to think that "Raspberry Pi = Easy" then promptly ran into early adopter pain combined with a general lack of knowledge. I'd like to see someone repeat this experiment, that was actually understanding of what they were getting into. Anyone with half a tick knowledge of RPI knows that it's not an amazing desktop machine, it's not supposed to be. It's a good "desktop" when you're in an environment that lacks significant technology access, infrastructure, and most importantly...power.
