I must say that, contrary to my initial expectations when I bought my iPad 2 two years ago, I find it far more useful as a business tool than I had ever expected, for reading, research, and E-mail. But Apple should have an iBook store app for Android and Windows gadgets if they are serious about selling books. Though I also have a Kindle and Nook, I read the books bought from both Amazon and B&N on my IPad, preferring the larger screen. But other people may prefer something else and why is Apple not receptive to this. I doubt that they would lose iPad sales since the iPad is, in my opinion, a more finished product (read the reviews on other handhelds).
