I screwed the base stations into a piece of wooden 2x4, and stuck the latter to the wall with two bits of Command hanging tape. Super easy. The kit ought to come with these pieces imo.
That's a lot of work for many people, and let's be honest many wouldn't even know how to do that let alone have have random pieces of wood in their house. Not to mention you've ignored all of the points I've brought up. I also really love external base stations. Nothing compares in terms of accuracy. Still I feel it's useful to not be so enamored with something that you're no longer able to look at them objectively. You've also forgotten the part about base stations being expensive and it's a hassle to go to the hardware store just for setting up VR.
