Wow. Many moons ago, I asked for the ability to have my audiobooks (generally provided by Audible.com) to magically sync up with my ‘printed’ (generally Kindle) books. While some people agreed that it’d be kind of neat, most didn’t see the use case, because you lose the story-teller side of the narration. However, I find that there are some books where the narrator, while pleasant and certainly easy to listen to, doesn’t actually bring that much extra to the tale, and I’ve been hoping for a way to continue with the story even after (say) going to bed – without inflicting the audiobook on my partner.
