you're totally right, I forgot to mention this. This is probably because I don't really like to read PDFs even on this, although they are certainly much better on the DX than on the smaller Kindles. I put a few scholarly article PDFs on there as well as a couple of musical scores, and they're not bad, but I think a tablet is better for PDFs. I seem to recall that there were two or three options for viewing the PDFs, including cutting off all the white space around the text, which would be a huge help except for most of the articles I read have a tiny footer across the very bottom that completely ruins this feature.
