Apparently, Wall Street was not amused by Amazon's fight with Macmillan USA. A bunch of the financial articles attribute the Amazon fall to expectations that e-book prices would rise. But that strikes me as nonsense. If that's true, why the big rise in Borders? Perhaps because some think that Amazon is not the future of online retailing and are looking for alternatives?
