Has anybody else used WhisperSync for Voice?
A few weeks ago Amazon introduced WhisperSync for Voice. You could always sync your Kindle reading across all of your Kindle devices (including Kindle for iWhatever, Android, BB, etc). Since Amazon owns Audible, they decided to syngerize this relationship on the Kindle. If you buy a select Kindle you get a discount on the Audible version (or vice versa). If you are listening on the iPhone or iPod touch app, Audible for Android or Kindle Fire the book will pick up where you were reading. When you stop listening and sync your reader you will pick up reading where you were.
I just started playing around with it: I didn't know that you can't use your iTunes library: it won't work like that. You have to download through the app and listen through the app as well. I'm doing this with one of the Kindle Daily Deals from this week, Six Days of War (about the Arab-Israeli war of 1967). It seems to work pretty well.
