Just to play devil's advocate, those $169 AirPods are by far the cheapest fully wireless earbuds on the market, and at launch were ~$100 less than the only other competitor available. Most estimates peg Apples margin on them in the low single digits...
Any references for this. My gut feeling doesn't match up with this. I can't imagine the bill of materials being more than 1/3rd of the cost?
Unless those estimates are including the R&D cost, I imagine these are low volume, and that Apple spent a lot of money on developing them.
And these are really tiny computers and highly optimized batteries, so I'd be surprised if the BoM is that low, but determining that is definitely not my strong suit.
I don't see Apple getting rid of them, especially considering the acquisition of Beats, but the AirPods really feel like the Airport base stations - setting a standard of quality to try and guide the industry along.
Maybe read their financial statements then?
(And I'm pretty sure they lost more money still for buying Beats that they've made from selling Beats products at the moment -- even though both was spare change for them).
So this point is not moot, much to the contrary, yours about waterproofing is: three years ago Samsung had a phone with: headphone jack, SD card, removable battery. Lots of other phones have headphone jacks and are waterproof. So that point is moot.
Lastly, I'm pretty sure the rationale for any company's decision is "to sell more stuff", not to "envision a future".
