This might be a pivotal moment on subscription based hardware. Apple is selling their hardware as a software platform _to_ companies that already sell their hardware. Will this force other companies selling dive computers to adapt and also use publish an app for Apple's platform?
As a diver it's clear to me that the target audience are future divers. We might delude ourselves on the pros and cons of our current dive computer, models and so on. But I am sure someone entering the sport will consider this along the other options.
My personal opinion, a big majority of recreational (shallow) diving does not even require a dive computer and it all comes into LARPing territory. It's good to know your depth and the time you spent underwater, that's all. I have seen people wearing a +1k USD dive computer diving at most This much money will give you a very nice dive computer, albeit terribly complex and completely overkill for most of the rec. diving. If someone is willing to spend that much on a dive computer for rec diving, I guess an apple watch is money better spent? Let's just acknowledge that a Shearwater Perdix is a tough sell to someone that wants to spend this much but dives very very occasionally and shallow.
I am just sad about the subscription model and the implications this might have if/when it proves successful.
