Sure, I'll take that bait. There are innumerable disabilities which might mean people have trouble manipulating small objects. That seems like an obvious reason for making it reversible for one. But congratulations for managing to do it half asleep in the dark (anecdotes don't make a convincing argument: I could share several contrary anecdotes myself).

But as for other benefits? There have been USB standards that have been deprecated because they were so fragile (I forget which–Mini?). The Lightning connector is solid, not hollow, and so seems more robust. The Lightning connector is also designed to support much higher power ratings than USB, so can charge devices faster.
