Its sad I've looked up old books on Amazon and come to discover via the reviews that there are counterfeit e-books on their platform. I would of thought that if I wanted an e-book of all places to look Amazon would be a pretty safe bet. I never did find the book I wanted on there. This is why I've sort of sought other alternatives. I enjoy my Kindle for reading when my iPad is just too much (laying in bed at night for example, I don't need all of my iPad if a Kindle suffices).
So I applaud any efforts towards improving online book purchases since, Amazon which is a tech behemoth built on top of online book sales cannot do its original task very well.
