i have a nook and you are correct, you can read pdfs on the nook. I had the nook android app but uninstalled it when i purchased my nook. I can't remember if you can read pdfs with then android nook app....seems to me that you can't, mainly just epubs. But like sitlet said above, it is easy to convert your pdfs into epub with calibre which is a free program for your pc...then just transfer it via usb to your phone. One cool thing that came out with the latest nook software update though is that all your nook devices/apps whether on a nook, your pc nook app, or android phone app, will sync. So if you stop reading on say page 219 on your nook, you can pick it up on your android phone later from page 219.
