Hello,
I just built an application that scans your public amazon wishlist and builds a list of all the books available for your kindle. You all should try it out.
So here's the story behind it:
I read a lot of books, and over the years I've built quite a list of books that I want to read in the future. When I bought a kindle about 1 month ago, I obviously wanted to read a lot on it. Only problem was that all the books on my wishlist were regular books. It was really frustrating to click through each book looking for a kindle edition. So I got my computer to do it for me.
If you keep track of books to read on an amazon wishlist, then you should totally try it out.

It won't work of you use the amazon shopping list. But it would be pretty easy to add. So if enough people wanted that I could add it.
