Valve has a history of bad hardware support.
What exactly do I need hardware support from Valve for? It's a PC for crying out loud. My self-built machine also doesn't have support from any hardware manufacturer and it works just fine and will continue to do so for many years to come.
I think many folks still don't get that this handheld is not a console and is not competing with one.
