And how does selling Nooks in Best Buy add into the mix? Money is derived from non-BN stores -- that's good. But identification with BN is lost -- that may not be so good.
Do EReaders promote reading books? Or do they supplant buying dead-tree issues? Since I was an avid paperback reader, going electronic resulted in less paper. Especially once I realized my allergy problems were tied to dust and mold from old books.
I note that many more books are available in a wider variety of media than when I was growing up. That augers well for the future of mankind. Read more, think more, be exposed to more of the world?
