IMO digital cameras are not "tech" they are "photography". Unless you're saying film cameras are much more popular than digital- but nearly the entire industry has left film behind, the same way "digital" LCD's completely left behind "analog" CRT's.
I agree, they don't quite fit into the list. I meant all kinds of cameras, including DSLR. It was just an additional electronic device many people used to own that got replaced by the increasing capabilites of a smartphone. Just like netbooks were replaced by tablets, and tablets were replaced by phablets. And now almost every single smartphone is of the size of a phablet (>= 5.5in).
