I have a first generation kindle, a kindle fire and I’m typing this on a Nexus 7. I love the Nexus unless I have to read outside. I use the amazon kindle app on my nexus and if I go to the beach I charge up my original kindle because it has the ink screen and bring that one because I can read easily in the sunlight. As for the Nook, I have only briefly looked at it in the store. You should go to a Barnes and Noble and check it out.
Thank you, Sawdring, for the comments. I appreciate your time and mature response.
Our problem is that there isn’t a Barnes and Noble within 200 miles from our home.
The Kindle seems to be far more popular from what I’ve read.
Best Regards
