Twice I've had people see my Kindle and ask, "Is that one of those e-readers?" Doh!
When I carried a PDA, I was invariably asked if it was a "Palm Pilot." No, it's a Psion. Then, when I had a Palm PDA, I told them, "It's a Palm, but not a Pilot." That usually got a blank stare. Then, everybody started carrying smartphones and the world changed, again. I have a box of historical electronic devices, none of which are Palm Pilots.
