Amazon announces Kindle Reader for Windows Phone 7.

Business Wire is carrying an Amazon press release indicating that Windows Phone 7 will be the next mobile operating system to obtain a Kindle Reader app, later this year. The app will include the standard Kindle features, such as whispersync to keep your place in the book you’re reading on whatever platform you’re reading it, and will also incorporate personalized book recommendations and the ability to send a recommendation to a friend without leaving the app.

Amazon certainly isn’t letting any grass grow under its feet when it comes to targeting the most commonly-used mobile platforms. It’s just one more element in Amazon’s strategy of remaining the most relevant e-reading platform no matter what platform you use, especially if you use multiple platforms.
