Zuckerberg's self-satisfaction and trim physique is quite a contrast to the frowning 40 something with a big paunch. LOL
As to the impact of the hardware, long term? Sure it will see some use, but won't be another iPhone, or even a another Facebook.
As HCB said, sometimes a great photograph is not needed. You are there with the camera, and that's enough. Without Zuckerberg, there is no "shot".
Would have been much nicer with a MM and 35 FLE 😉
