Someone gave me a Kindle about a year ago and I found that it can read PDFs OK -- however, there's a fundamental flaw that I believe Amazon deliberately put into the tool: the links in the PDF are not clickable (when, for example, they are on a PC). I suspect this feature was crippled deliberately to reduce the attractiveness of PDF for content delivery, as that would allow other people to sell content and reduce Amazon's revenue. Of course, I have no proof of this, but since I generate and use technical PDFs constantly, it was just about the most important feature I wanted in the Kindle, as I have hundreds of PDF documents with links. Navigating them with the Kindle is very painful to the point of making reference documents nearly unusable. Because of this, if the Kindle had not been given to me, I wouldn't purchase one for myself.
