We got the Nook a few days ago. My son was SO excited... but we are sending it back.

The whole idea with the Nook purchase is that it had built in PDF reading ability, plus you can add storage with a micro SD card.

Well.... it reads PDFs if you like looking at microscopic fonts on the screen. It shrinks the pdf page to fit the reader, which is not a good thing. It does not break the text into panels, so that you can read like the other book formats. Graphics become invisible. If the PDF text is is columns, it's even worse as the columns are now in microscopic fonts.
Sure you can zoom panels but it's VERY difficult to read with any flow as you have to select which peice of the PDF you want to zoom, read it, zoom out, select the next piece... you can't page through them.

We spent some time googling comments since people have gotten theirs this week, and the overall opinion on the PDF capability is thumbs down, from professionals trying to load and read journals in PDF form, to out of print books. We did call tech support, and nope, the PDF format is not going to change anytime soon.

We are VERY disappointed. The whole idea of this thing was so my son could load his 30 GB of out-of-print specialty books in PDF format onto it, and textbooks.
