1 App I'd Like to See in the Apple iPhone App Store - A Kindle KIller

The release of the 3G iPhone on Friday is overshadowing a more important iPhone release the same day, the Apple iPhone App Store. I have high hopes for the store. Back in the day I had dozens of applications on my Palm Pilot, Palm III, and Palm V. All were simple little apps that did one or two things very well.

Here is one App I'd like to see:

A book reader that reads several formats: txt, doc, pdf, and the Amazon Kindle format. I used to be able to drop Web pages, documents, and PDF's into my Palm V and read them in a simple auto-scrolling reader. I'd like to do the same with my iPhone. A bonus would be if somebody write an app that let me buy Kindle books from Amazon, so I could have the Kindle experience on my iPhone. Would Amazon allow this? I'd pay the same fees, just not buy the Kindle, and I get the impression that Amazon makes no money on it anyway. This would be Kindle Killer.
