My honest take: I can’t wait to use Steam Frame. But it needed to launch 3 years ago to move the needle on VR beyond hardcore users. The industry is in the midst of a transition to a new class of headset, and Steam Frame already looks dated at launch.
I respect the people at Valve for building the thing they personally want to use. I think that ethos will make Frame beloved by a particular group of people, but that group probably isn’t going to grow substantially beyond where it’s at now.
