The device itself looks quite nice, and it might even be one of the best VR/AR headsets out there.
But that's a bit irrelevant.
The important thing is that Apple created a whole new marketplace, a new category of apps, and that ecosystem will have a chance to change things, just like they did with the Apple Store for the iPhone. They will probably force all apps and accessories to only work with their own branded devices, as they tend to do.
This might help create a new alternative marketplace for open source apps, etc, but I'm not sure about it.
