you seem to be confusing an operating system for the user interface. An os can (and regularly does) have more than one interface. In this case steamos ships with two of them. One they designed which is targeted for games. And they also ship plasma as a desktop environment for those who need it. The operating system lies under all that, and you can launch any piece of software from either of the interfaces. (or the terminal, that counts as a 3rd way to interact with the computer, I guess)





they are legally obliged to have a backup strategy, no?
