I see Kindles all the time. Sonys I've only seen once or twice and never seen a Cybook other than my own, or any other dedicated ebook reader. The same people tend to take the same trains each day, so I see the people with the Sony and Kindles on different days, but that one day it was like a perfect storm of liseuses.
None of them ever ask me about my Cybook, though.
I did a lot of flying this past month and I don't think I saw any other ebook readers. Laptops and BlackBerrys everywhere. So theoretically I suppose some could be used for reading.
