The Kindle can be read outside. You have choices of the type of print you have like black on white or white on black etc. Dh has the Kindle Fire and loves it. It picks up WiFi and you can use it like a laptop with limitations. DH watches his Netflix shows on it with ease. He was in the hospital for 3 months and used his Kindle more than his laptop. He said it was just "easier". I am no youngin' though young compared to some, I guess and old compared to others. I am passed middle age. My Galaxy s3's screen is about 4-1/2". Yet I still find myself enlarging thing all the time. It has a lot bigger screen the the IPhone. I have good strong reading lenses for both near and mid distance and a great eye doctor!
