It's quite predictable. This is the same story that's been told over and over: "it's really cool but not really practical". Pick it up and play with it for a few weeks, then get bored and never touch it again. iVR certainly moved VR forward but it didn't solve any of the fundamental problems that VR has had since its inception.
VR has 1 practical application, and that is gaming, and Apple has very little in the world of gaming outside of super basic 2D games.
