No one... and I mean NO ONE... has ever stopped and asked me about my reading on my PDA. Including people on the train, reading their paperbacks and hardbacks right next to me. Sometimes I feel like there's something about what I'm doing that makes people pointedly
avoid asking me about it. Maybe they're afraid of hearing how good it is. Or maybe geeks frighten them. Maybe I look too old to be playing with toys. Maybe it's my deodorant...
I think at this point, most everyone has heard about the readers, and either are interested or aren't... and it's pretty much just the people who are already thinking of getting one, and see yours up-close, who ask about it.
