This. I don't like reading on my iPhone for any extended period of time, but it's fine for reading for a few minutes when I'm stuck in a line, waiting room, etc. Conversely, I really like reading off the e-ink screen of the Kindle, but it's too big to lug around with me everywhere. The ability to sync so that I can pick up right where I left off on whatever device I'm using at the moment is the really killer feature - it's like living in the future.
I hope B&N's implementation of this works as well as the Kindle version.
