I'd love thick phone with big battery, the current ones are already thin enough to be uncomfortable without a case, but the available models seem to be "ok if you want battery you want some rugged brick 3 android versions behind with everything else worse"

I don't know a single person that would dive with their phone or care about the thiness of the bezel.

> 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.

I know plenty. But not among the 18-20 year olds that do not know it any different, sure. But certainly my grandpa. Just thinking that you do not need a power-bank and just bring an extra battery on a longer trip will get millions of people interested.
