> camera makers should've begun adopting Android at least a decade ago That would be horrible. So now my camera would need a constant stream of security patch updates (which the manufacturer will stop supplying). And surely use a lot more battery. What I love about Nikon DSLRs is the firmware is just for taking photos, hyper-optimized for that. There's no baggage. And it will keep working forever.
