When I open the same book on the Kindle again, I have the option to pick up where I left off either on the Kindle or the Mac. Improved WhisperSync support means that I can read a book on my Kindle, open it on my Mac, and it will open to the last page read on the Kindle. Actually, I'd just downloaded the brand new app a day before it had been officially announced. I thought I was hallucinating, or my memory was faulty.
