They do have the only VR set that is user friendly enough and has enough ecosystem and apps for mass market. When they put out a future generation with lower prices, they'd get as much as possible.

Let's not forget that the iPod was a Mac only product, when the Mac just had like 3% of the market, with no Windows support and limited sales in the first versions. Or that the iPhone took a few years to dominate the market. Blackberry, Nokia and Microsoft even thought they had a chance for 3-4 years.

I wouldn't be surprised if their VR sales are already above all the other players (perhaps even combined).

The VR space doesn’t seem settled to me. And I think Apple could win — having tried most of the major models, Apple’s is noticeably better. It really does feel like magic (other than the weight).
