Nothing.
I bought the reader for web-content and public domain books. When I buy books, I still go for paper version.
My position might change if bookshops disappear the same way record shops did. I sincerly hope they won't. I still like books. And bookshelves look good in my room. Besides I own books that have been in the family for a few generations. And I doubt my ebooks will last even until next generation.
The disappearing of paperbooks would make it too easy for "1984"-like re-editing of the past.
