The Frame is the only one I care about. I was debating on getting a Quest 3 since my Quest 1 is having issues, but this would be a great alternative depending on the price.

VR is a niche market with fundamental accessibility flaws (motion sickness, spatial requirements, etc.). As for the controller, what discussion is needed? The steam deck already exists and from that it's pretty easy to get a decent idea of what the controller will cost and feel like. It'll probably end up being a solid controller for people that want it, but uncomfortable for people with smaller hands.

That isn't to say that the steam frame/controller won't impressive pieces of technology, but should be pretty easy to see why discussions would mostly be around the steam machine and specifically its pricing. Its success (or failure) will likely be what carries the reputation of both the steam frame and the steam controller alongside it.

The Steam Controller also had a failed attempt in 2015 so I guess that's also out of the question then?
