I read a lot of 30-40 page PDFs (research papers). I usually print them out, but I purchased the Surface Pro because I like the idea of marking them up electronically in OneNote. Marking up PDFs in OneNote is a dream: I have all the space I could ever want for notes, the surface pen works great, and life is good. There is just one drawback: I can't stand reading PDFs in OneNote. There is just too much background stuff going on that makes for an unpleasant reading experience. When you're reading research, you honestly don't want to see anything but the research. The PDF Reader that comes with the Surface is a lot better for reading. The Surface Reader portrays the PDF and blacks out the sides making it seem like you're reading normal paper. You can mark up the PDF with the Reader too, but you don't have the extra space on the sides to take notes. I take a lot of notes so this is a deal breaker for me. I need something that merges the readability of the PDF reader with the note-taking ability of OneNote. If there was just some way to extend the white space on the PDF reader so I could take notes, that would be amazing. Any ideas?
