Kindle eBook reading app is now available in the new Mac App Store, and is already the fifth most downloaded free app.
Amazon is pursuing a “buy Once, Read Anywhere” strategy with the Kindle, with the idea that once you download a Kindle book, you should be able to continue reading it on any device. You’ll have access to over 775,000 books in the Kindle Store, including best sellers and new releases. Amazon Whispersync automatically syncs your last page read, bookmarks, notes, and highlights across devices (including Kindle), so you can pick up where you left off on another device.
Kindle already launched Kindle for Mac last March, but this version is distributed through the Mac App Store which is part of the latest update to OS X.
The Kindle apps for the iPhone and iPad are also getting an update which gives users access to millions of free books, better image zoom, and the ability to download books in the background while you are doing something else.
