Now this is sweet. Amazon has upgraded their Amazon Reader so that if you purchase a paper-bound book from their store, you can get an on-line version of the book for an additional charge. The on-line version is readable through a browser wherever you are, which might put a dent in other eBook publishers wallets.
Even better yet is the ability to interact with the book as if you had the print version. According to Amazon, you can "create highlights, bookmarks, notes, and tags; copy text; and print pages of the book." Will this model kill the standalone eBook reader market? It might not bring extinction, but if the Amazon model continues to grow in tandem with wireless data access, why would anyone purchase a device solely for reading eBooks?
