Honestly, I'm kinda surprised it's still that expensive. My school just got a WMR headset and a Vive headset. The only differences between the two were that the WMR didn't make you mount sensors on the walls, the WMR's controllers bug out a little when they leave the fov of its cameras, and the WMR looked better. The Vive played slightly better (though it was rare that the controller camera bug caused me problems on the WMR), but the WMR played well enough and looked good enough that the Vive's price just feels like a ripoff. The only real big advantage I can see the Vive having is more support for different games, but even then I think the tools devs have access to are improving enough that this eventually won't be an issue.
