I'm starting to get back into reading and I'm enjoying it. I'm trying to decide which eBook ecosystem to dig into. Several of the book series that I'd like to read have 20-40 books in them. And I usually read about one book per week. My goal is to be able to read on an e-ink ereader, a Smartphone, and be able to listen to the audiobook version. And for them all to sync progress. I recently experienced this exact thing through Amazon with their whispersync. It's perfect and seamless. And super expensive for someone that reads one book per week. So I'd like to find an alternative. Kobo with Overdrive support seems close, but doesn't appear to offer the progress syncing that I'm looking for. Can you guys make any suggestions of alternatives, or is Amazon the only one that does this?
