Amazon recently announced the launch of its Kindle app for Windows Phone 7.
The app comes features like ability to browse, buy, read, annotate and sync books across devices, and two minor features not yet available in any other app: personalized shopping recommendations (available on the home screen) and the ability to send book recommendations to friends.
“With Kindle books you never have to worry about what to do if you change devices or platforms. Our free ‘Buy Once, Read Everywhere’ apps make it easy for you to read your books on any device you choose – your Kindle, Kindle 3G, Kindle DX, iPad, iPhone, PC, Mac, BlackBerry, Android-based device, and now your Windows Phone 7-based device” said Dorothy Nicholls, Director, Amazon Kindle.
