Pros: eInk display preserves traditional reading experience and has great clarity and contrast. Reads PDF (both scanned and standard text) and EPUB book formats with no hassles or conversion required. In-store help and extra features from B&N. Page turning speed is much improved with most recent update. Android OS allows for almost unlimited software improvements and added features. Replacement batteries can be bought and installed easily. Accepts SD cards for increased storage capacity (this really comes in handy if you want to use the device as an mp3 player or for audiobooks).
