An electronic book that works?

Unfortunately no. At least not with content purchased through Amazon. You can copy non-Amazon items directly from your computer to your Kindle and Amazon won't know a thing about those.

Amazon did, at least, recently add a feature allowing you to abandon your rights to a book so that if you spent a year reading nothing but reading things that would now embarrass you and you want to share an account you can "delete" them. But then if you want the books back at some point you'd have to rebuy them.

The top three features I'd want from Kindle that I currently don't get are:

1. Folders so that I can organize the books on my Kindle in more useful ways than is currently possible.

2. Create a "used book" marketplace. Amazon could say "if you want to sell your ebook, the minimal price is $2 with $1 to us, $1 to publisher, how much do you want to add on top of that?" and then allow transfer of rights. No, not a direct correlate of the existing used book marketplace but something I think would have a greater chance of happening.

3. Separate device permissions. That way a family could link multiple Kindles to one account to share purchases but Dad could still keep his Best of Penthouse Forum off limits.
