It happened to me at the airport a couple weeks ago. The gentleman beside me kept looking at it, then finally asked about it. He had a lot of questions and like LDBoblo I really just wanted to read my book, so I answered most of his questions, telling him how absolutely awesome it is. Then he started asking about the Kindle-I do not own a Kindle, do not want to own a Kindle, so I just told him about MR, that he could find the answers to all his questions here.
Then I finished my book.
It doesn't happen extremely often, except at work, but when it does happen the people asking usually mention wanting to get one for a relative for Christmas or something after I tell them how nice it is.
