Well I think most of you are wrong when you say people these days read less.
They read a lot more the content might be different but they do read a lot more.
Twitter, facebook, sms blogs and most other internet use is still mostly textbased so the amount of reading is more not less.
You have authors that are making millions of dollars and their main target audience is a generation that from what I gather does not read anymore now thats amazing.
So any cheap device that can support all these diffrent media will result in more readers.
Not of books maybe but the media that is of today.
