One thing that I keep hearing, is people trying to figure out if Live Photos are a gimmick or not. No one has had access to Live Photos long enough to know for sure, but I can say, that when I get little moments like you see in the video of a live photo below — well that makes it something I will always cherish.
(Should be on Vimeo soon if this embed fails on you.)
So far, it seems Live Photos are anything but a gimmick.
