I'm on PC at least 75% of my time and not on my phone. My phone is mostly for messaging, music, email, and killing time at the airport/airplane/wherever I'm waiting. I get the point about extremely long URLs though, but most of the time that's not an issue unless you're printing it out

Depends on your OS, manufacturer, and version. In Android, it depends on your camera app (and version). Later Google Camera versions have that, for example, but earlier ones (as of a few years ago) did not.
