I have a Pandigital. LOVE IT! It comes with wi-fi. I can download from the library, plus all the free ebooks from Barnes and Noble. It also has a calendar and several alarms. I usually pack 5 books if going away for a week, now I just take this. My husband has the Nook (not the color). He got it before I got my ereader, and wishes he had the Pandigital. It was a lot cheaper.
The only bad thing about the Pandigital is the lack of cases for it. So after searching the internet, I made one. Here is where I found the directions.
