Has anybody had positive expereince in using Nook to read curriculum? I have the 2nd generation Nook and it’s also rooted for Android on a 32 GB SD card. It’s 7" and a little hard to read regular PDF files and I have to put it in landscape position to read with comfortable font without scrolling horizontally for the same line. Those specially created eBooks from Barnes and Noble can be read with the Nook in portrait position.
