If Apple goes all-in on VR, the whole VR market will benefit from greater public acceptance. But at the very best I predict it'll be like the Nintendo Wii: a few games that are extremely popular, and then it gets old.
Which is a shame because I agree that Apple is in a great position to enter the gaming market. Imagine what Nintendo could do with powerful hardware in so many hands! But by the same logic, Apple should have crushed Spotify long ago, given its mile-wide lead with the iTunes Store, and yet the nicest thing I have heard about Apple Music is that it works with other Apple stuff. I honestly don't think Apple's management understands entertainment.
