There's pricing to the existing market devices, and then there's redefining the market. Apple has a history of successfully disrupting existing categories. They weren't the first, they just executed it better.
The "firsts" are always expensive when compared to the products they're about to replace, and for the most part shouldn't even be compared against each other...
The first DVD players must have appeared ridiculously priced compared to VHS. Same for the first LCD flat screens vs. CRT prices. Just give it enough time, laptops will cost more than the best VR headsets soon enough.
