I just had to post a reply saying that soPdf is
awesome. Technical PDFs were nigh unreadable without it. Either everything is so small I'd get a headache from reading it, or I'd lose formatting and not be able to read diagrams and code snippets. Thanks to soPdf, I can actually enjoy reading coding books on my PRS-505. Now this should hold me over till the Plastic Logic device shows up.. Thanks, soPdf author!
