I suppose you could exclude non-standard books from the total but that is hard to quantify. Unfortunately it is the nature of marketing for some companies to try and garner success by using a closed door approach. In the long run I think this will hurt, rather than help the market as a whole. Monopolies are not a good thing IMHO.
And Amazon is now selling some eBooks that are not for eink Kindles. The enhanced eBooks do not work on eink Kindles.
