To expand upon why: I have a medical condition that makes hard things touching and moving around my head painful (and more!) and the Vive seems to be the only headset that's pure elastic & rubber straps with a nice face cushion, so that pretty much makes it the only choice for me. And demand for these VR headsets seem to be pretty strong, so I doubt they're going to be REALLY CHEAP anytime soon, and the longer I wait on the Vive it seems the longer I wait in general so....
Now I wish I impulse bought it. :|Welcome to the club, now for the agonizing wait lol.
