It's a little plain and slim on features, but the free Kindle app for Android does its job as an e-book reader. Once you fire it up, it lets you shop for new books or download books you've already bought through your account.
Since Kindle is about book sales, the app lets you buy e-books through Amazon's online Kindle Store, where works typically sell for about $10 a piece. A much-needed and hopefully cleaner-looking and quicker-operating in-app store is reportedly coming in future versions. If you're unready to commit to a book, you can wirelessly send yourself the first chapter for free.
The app's straightforward navigation has you tapping in the margins or swiping the sides to advance through the pages, either in portrait or landscape modes. Press the center of the page to remind yourself of the book's title or check out what percentage of the selection you've read. As with Kindle on other platforms, this app will remember where you put your bookmarks, though it would be nice if we could rename the bookmark, rather than try to remember the assigned location.
Unlike other e-readers, the Kindle reading pane is plain white by default, though the settings let you adjust brightness and font size, and choose a smooth sepia or black background if you're not a fan of the white. Hopefully Amazon will add other textures and colors to enhance the experience.
