In some postings last year I discussed many teachers feelings of frustrations with coursebooks.
A friend of mine, visiting from the USA, told me that many professors in universities have stopped using commercial textbooks and make their own books for their students. Indeed, while obviously a great believer in the coursebook, while visiting China, Jack Richards, the other of Interchange by Cambridge University Press, said there was a growing movement in Australia to not use commercially prepared coursebooks. He said that people are beginning to think you are not a very good teacher if you have to use a commercial coursebook.
I recently came across this podcast by Richard Baraniuk, a Rice University professor, with some brilliant insight about the possibilities of what life would be like after commercial coursebooks.
