I have a vive, and my lighthouses are on collapsible tripods that sit in corners of my living room when i'm playing. Takes ~5 min of time to set both up, point them in the right direction, and setup room boundaries in Steam. Works really well, if you prefer to do it that way! I think I would still prefer inside-out tracking, but I have very specific reasons for only using the Vive, so that's what I'm stuck with. I think it's a problem that can easily be overcome if you're interested in this headset, without having to drill holes into walls! It's definitely an extra expense though.
However, if their whole goal was "smallest lightest headset" then you can't really blame them for removing every single piece of tech from the headset they possibly could and outsourcing it to another device to maintain that claim. The right call? I dunno. But if this headset can be a drop-in replacement for my Vive one, I will buy the hell out of that. It's a strict upgrade for me with basically no extra expenditure of effort/money beyond the cost of the headset.
To each their own though!
