If I was going to wish?

First, make it tougher instead of pretty. I LIKE taking my ereader with me. (Hmmmm, rubberized texture and water resistance.)

Second, 2 memory slots. Yes, I said 2. One for storage and one for reader program hooks so that whatever program needed to read with can just be popped in like a game cartridge. (Hey, if they insist on a different reader for every book and every font, might as well just load them when you need them.)

That's two wishes. One for each hand. Oddly enough, they don't seem any fuller than before.

As for reality, agree with better file organization and some sort of document navigation ability.
