Considering the immaturity of the ebooks market, price variability seems like a good thing. Increased margins (whether the result of higher or lower prices) will let publishers experiment with better typography, lesser known authors and more interactive works. The last thing most of us would like to see would be the ebook market turned into a numbers game such that only mass market paperbacks, poorly converted public domain material, and amateur self-publishers ever get access to the market. How would we have reacted if Apple had announced a $0.99 ceiling for the AppStore?
