Airport security do this - say iPad when they mean tablets. They also get upset when I leave my kindle in the backpack

As I recall there was also an incident when Microsoft sponsored NFL broadcasts and gave the casters Surfaces and they still occasionally called them iPads.

And I have gotten scolded for pulling my kindle out to be scanned.

You can't win with security people at the airport.

To a lot of people, there IS no difference between an iPad and a tablet.

To a lesser degree, there's the same confusion about iPhones being a generic term for any smartphone.
