I've actually tried DropBox for photos, and it's actually pretty awful on this front. Our company just switched from Box to DropBox (because of DB Teams issues), so I have little reason to stay on DB outside of my photos... Someone will come along and do this better (and they'll win this space starting mobile first).

Don't know if the winner will be Loom -- But the "why is there yet-another?" could've been the exact same question for when DB launched. "...Because people feel like the problem is still not solved."

The bigger problem we're solving is not just photos, it's being able to access and edit content fluidly and seamlessly across devices and on any screen. We're starting with photos and videos as they take up most space on your devices/computer.

The short underlying answer is that it turns out that this is hard.
