Pax Prime looks like it was pretty good for Valve and Steam machines, as Robin from Valve did a little chat about the Steam Controller, and behind him you can see a big Alienware Steam Machine section, love it.I really do love the idea of what he's talking about with reloading, it sounds like it's going to be a very useful gamepad.
