I bought the Kindle DX specifically for this purpose. The size and general text comes out well for Kindle format books. However, the PDF experience is really lacking. You can zoom in on the pages and exhibits, but it is not intuitive. If you have a PDF that has significant margins on it, it really starts to lose its appeal. I have found myself using an iPad pdf reader or my laptop quite a bit more than the Kindle DX for reading PDFs. Having a color screen also really helps for the code sections. I probably wouldn't have bought the DX if I knew what I know now about its abilities within the PDF sphere. It does a great job with ebook formats, but my books are split 50/50 between PDF and ebook formats.
