When you think about it, Gabe's pissed at Windows for turning itself into stuff, and he wants to move Steam to Linux to save PC gamers in a way.
He DOES, however, have a stuffload of experience making an operating system. He was basically the lead behind developing the first 3 releases of Windows.
What would the PC industry be like if Valve released a PC-gaming friendly Operating System for Intel-based systems? Discuss!
