The biggest problem with this is that my wife and I share our Amazon account. Although we have our own Kindles, we use the same Amazon account because we're not going to buy two copies of every book that we both want to read. If we had to do this, we would probably buy the paper version. So, my "stats", highlights, and my account information include everything she has done with her Kindle.
Until Amazon lets us have separate accounts (or somehow separate our reading), this will be relatively useless for us. We can't even separately rate books, or mark books as "hope to read", "reading", etc. and we're not going to buy double copies just for that purpose. I suspect this is the same for many others.
