I tried the whispersyc feature on a book (Small Gods by Terry Pratchett) that we were reading for a book club, and found that it didn't sync at all between my phone and my iPod (my primary audiobook listening device) and only imperfectly between my phone and my kindle keyboard. I wasn't terribly impressed, certainly not enough to try it again. It was too much of a pain to keep trying to sync my devices to the internet and Amazon all the time. It's just as easy for me to listen to one book while reading another.

On the other hand, getting books at a discount that way is appealing, and I'll have to check it out next time I go to buy a book in both formats (which is a fairly rare occurrence).

ETA: I just bought Calculated in Death in both paper and audio, and this feature wasn't available to me anyway.
