I love "whither the e-book" stories. All of them (including the one I helped write and which was just translated into Spanish!) contain some variation of the line: Wouldn't it be great to carry around the book you're reading now, your next three books, a couple books you don't know if you want to start or not, including several heavy classics you've always meant to read, plus all your contacts and emails? All in a package weighting less than 8 ounces?

Right now on my Palm, I have all that. The tough part is remembering what's on there, what I read already, and what I thought about it. I'm not a huge keeper of reading lists, but I'm consuming e-books at such a rate that it seems important to keep a list.
