pdfs on the Sony Reader

Some user-generated pdfs work fine on the Reader. No resizing, of course, but the page-turns are quick enough and links work fine. Example book Oliver Twist from beta.feedbooks.com. Also another "Survey - The Brain from the Economist" which has some illustrations too. Transferred using PRSUtil (works fine after .NET framework was installed) and Connect reader SW - in both cases, the results were the same.
