That heatsink pad in the main processor really looks crappy/crummy, with a reduced contact to the heat-sink..

A few years ago we went kayaking in a very dark lake to recover a GoPro with the headstrap still attached but it didn't work. The bottom of the lake was probably rather large rocks that anything can hide between.

This pool, as are most in the sandstone blue mountains, sandy bottoms. So the camera could eventually bury itself in the sand.

The way the front fixes it looks like dirt could work its way in there. Seems like a crude design for something to be use on the go, where keeping things clean is nearly impossible.

I was rather surprised that the thermal pads didn't seem to make better contact - it just seems to have flowed a bit between the surfaces on the main SoC, and the rest looks untouched.

Someone could make some money selling buoyant headstraps.

Ineresting comment on heatsinking of the sensor to the lens body. Perhaps its a there to provide heat to the lens as anti-fogging, perhaps as a secondary benefit, or maybe a main purpose.

That looks useful but it would still be cheaper to make a headstrap that floats. Of course if the camera dislodges from the strap the floaty backdoor is better.

An excuse to get the 4K version (when it becomes available), evaluate how good the 4K quality is, and then do a teardown?
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.
