Occasionally - people at my library have asked, and people on the bus. Usually, they ask, "Oh, is that a Kindle?" and then I explain that while it reads ebooks, it's a different model of reader.
Most of them just get confused, but one person actually was like, "Ooh, why did you pick that one? I've been looking at a bunch of readers and trying to decide which one to get!" so we had a nice discussion about different models and what they do.
