.@Sven Groot: Thanks, that's good to hear. I think mostly I'll be using it for reading PDFs of papers and the like, so it sounds fine for that (currently I have a mini rainforest on my desk because I refuse to read them on an LCD monitor... ).
Actually, reading PDFs is just about the one thing I don't like to do on the Kindle. The Kindle's screen is way too small to show an entire A4 page, and scrolling through the page is awkward (though at least less so on the newer Kindles with a touch screen). You really need something in a format that allows reflowing the text for smaller screens.
