@BitFlipper: "However just like all previous attempts to make a Linux console, it will fail because ultimately those that choose Linux out of "principle" also don't like to pay for anything (it's their God-given right to get everything for free and whatnot)."

Well, time will tell how Linux users behaves in Steam but at least in HumbleBundle Linux users has been paying quite nicely so far.
Steam Box is not going to be the only Linux console that is trying to get some market share this year as there's going to be plenty of Android devices as well.
