Steve Jobs' biography is coming out on Monday and since I haven't made any commitment to either bookstore, I can start fresh. Which bookstore are you guys using? The most important thing for me is book selection and price. How are the book prices in iBookStore and how does that compare to the Kindle Store? I don't have Macs at home, but I do use an iPhone 4 and iPad 2. I know one of the advantage of the Kindle application is that it's platform agnostic. I know that I can load up the Kindle Store application in Android and continue reading from there. Other than that, are there any advantages of the Kindle Store to the iBookStore? Even right now I've been trying to be platform agnostic because of the fluidity of the mobile sector. I don't want to be completely locked down with iOS. This is why I don't use iMessage and use Facebook Messenger so that I can continue the conversation with another platform. I do that with some other applications as well. Do you guys have a compelling reason to use iBookStore over the Kindle Store? Thanks!
