I guess we all know that ereaders are not real books

But still, they get close enough (at least for me). I love that my Sony doesn't smell like some 2nd hand books. Also I love just laying my reader down without having the book closing itself and forgetting to put a bookmark before. You probably know these occasions: "Daddy, can you come to my room and have look on this or that...", or the doorbell or phone rings....
So yes, I think it really doesn't matter and everyone can find the device he needs, even if it is the old school pbook.
