This is where I think Steam machines can really shine. Console gamers don't want to deal with the sort of stuff in the article, a vast majority of them may be intimidated by it as well. Also with setup, there's dealing with viruses, corruption, and backups. Although not much of a problem in reality, these aren't the sort of things that console gamers want to put up with, rather just turning on their systems and playing right away.
I think Steam machines could really take off here, being a hybrid of both a console and a PC. I believe some models of Steam machines allow the user to upgrade its components as well. However, at the moment Steam OS is limited mostly due horrible pricing on what seems to be the majority of models. It could be said that games are a limiting factor as well but that's improving rapidly.
