Sticking with paper?

The book world might well be looking over its shoulder at what is happening in the music business. As Keane becomes the first band to release its single, Nothing in My Way, on USB memory stick you wonder how long it will take before the first book comes out on memory stick to encourage people to use products like the Sony Reader.
It certainly offers the potential to add things like author interviews (video as well as text), a biography and other material that will add a great deal of value. Who knows when The Guardian will get the chance to write about books on memory sticks as well as music?
