Agreed. Easy to use UX is what sells tech and gets it used en masse.
Pretty tangential, but I observed that exact phenomenon recently after looking at the recent VR headsets: Oculus Rift and HTC Vive existed for at least a few years. Tried them, was pretty fun, but tangling with wires, having to have a powerful PC on hand, that 1-2min set up every time before you want to use it, it was all killing the usability for me.
Then Oculus Quest comes out earlier this year. Pretty much similar tech (a few differences, no need for PC, but can be used with one through easy sideloading), but no wires and no need for a PC connection. Every time I want to use it, I don't need to fiddle with my PC. I put the headset on, it wakes up in a few seconds at the exact spot I left it last time. I put it down, it goes to sleep in 15 seconds.
I ended up spending an hour or two almost every day for the past two months playing with it, as opposed to the previous headsets (most of which were left on the shelf a few weeks after the initial purchase). The only major advantage that Quest has over previous gen is easy and frictionless UX.
It got to the point where every single friend of mine who tried it at my place ended up purchasing their own headset the day after. And those people were some of the biggest VR skeptics, after their experiences with original Vive and Rift.
