The PDF conversion utilities are certainly interesting, especially the PDF Extractor which I've briefly tried. Interestingly it did not try installing any third third party products, toolbars, etc. unlike the dreaded Flash and Java updates.
What I really like about the PDF Extractor is that it appears to export the original images from the PDF, whereas when trying to use the snapshot tool in PDF-Xchange (which I use instead of Adobe), there's no way to get directly at images that have text or other objects overlapping them, let alone the original image quality. I always had to use Inkscape whenever I wanted to extract the actual images and even then it was quite a cumbersome process, especially when extracting multiple images.
I am curious to see how well the font-extract feature works. I have been looking for a tool that could extract fonts from PDF files. For example at work if I need to make changes to a PDF, generally I can get hold of the original editable version from the client, but if they're using a Mac, there's a good chance they're using a font that my PC doesn't have. So it would be handy to export and install the font from the PDF to let me modify the editable document the PDF was created from, without writing an e-mail explaining what text on which lines need to be revised and why I couldn't make the changes directly in their document.
