Better than kindle
Just got this app because I could not get a certain foreign language book on amazons kindle. I looked on google play books and there it was! Not only was it once click away from owning it, it was about 25% cheaper than amazon or other online book stores I visited. After installing the iPhone app my purchase appeared right away. Am also happy with the features of googles ebook reader. The slick page flip animation is just the icing. The fact that you cannot purchase an ebook directly through the app is valid also for kindle and is due to Apples restrictions in app design. It doesnt really matter since you can open a browser, log into google play and get your book. It will then show up in a sec on your iPhone app. And if you are lucky way cheaper then from other stores.
