With Amazon having built Kindle applications for iOS, Android, and BlackBerry, you probably could have guessed that they had plans for a Windows Phone 7 app. Sure enough: this morning, Microsoft and Amazon are announcing that the Kindle application is on the way, with an always-helpful launch date of “soon”.

As far as we can tell so far, the Kindle for WP7 app will tout just about every feature that Kindle fans know and love, from automatic page syncing to the ability to purchase books right through the app. The only thing missing? A little tiny man who can convince me that reading books off a tiny screen isn’t a terrible way to read. (Ba-dum-cha!)
