why not just use adobe reader? that is what I have on my Nexus SEver since I've had an Android phone phone I've been on the hunt for a really good PDF reader. I think that search has finally come to an end. ezPDF Reader ($0.99 on the marketplace) is easily the best PDF reader I've used so far. I've tried the official Adobe app, the free version of Quick Office, and I also purchased Document-To-Go which has a built in PDF reader. While those programs are fine to view PDF's a couple of pages, they are basically useless if you want to read PDF's with hundreds of pages. The problem with them is that they do not save the last page you've read and you cannot create your own bookmarks on the app.
Now with ezPDF Reader I can create bookmarks and the app will remember the last page I've read. This alone makes it worth the 99 cent price, but the app goes even further. You can double tap on an block of text on the PDF and the program will automatically zoom in on that text to fit the width of your screen. You can then easily scroll the text up and down without accidentally moving it left and right. I find this method better than the reflow method of other readers (but it also has text reflow if you like that). You can even copy text from the PDF. As far as rendering pages are concerned, I didnt find it any faster or slower than other PDF viewers, so expect the same type of performance as the other PDF readers I mentioned.
Anyway I posted this in the Nook forum because the bultin PDF reader is crap and it makes sense to have a good PDF on the Nook. This makes the Nook much more usable with PDF's.
Just found this video on Youtube showing off ezPDF viewer on the Nook:
