Just because the magnetic properties came up in this thread: I doubt Apple designed it this way, but an ipad pro with their keyboard folio will stick to the metal walls found in your average restroom.
Same with the Smart Cover! I recently just found this out too, I can stick my iPad on the side of the fridge and plug it in and have a nice smart screen for family calendars, Siri / whatever
Eww.
I'm not proud of that discovery, but it was that or leave my ipad on the table at my local chinese restaurant.
