Torwan, maybe this is because you live in Germany and here Kindle isn't a synonym for eReaders yet (if any brand is connected to eReaders at all then I would think it's Sony).
What I observe regularly: in my library there is a very small exhibition of eReaders for testing and everytime someone comes testing them they start rubbing vigorously at the screen and being very disappointed when nothing happens. They treat them exactly like they would treat an iPad!
