> I don't think any single person I know would say they would exchange replaceable batteries for a 1mm thinner phone, waterproof up to 100m instead of 10m, or a $5 difference in price.

Well, yes it's quite easy to argue against strawmen. I don't know anyone who would favor a built-in shoehorn over a replaceable battery either.

Although on your waterproof point, that's just a single dimension metric used for comms. It's not really about specifically descending to 100m. A 100m rated device responds better to water. In a general sense, it's more robust. Even if I don't go diving.
