For the past couple years I have been experimenting with Amazon's Kindal Reader. It takes getting used to and not like holding a book in your hand, but has great benefits of vast resources really cheap. I like that I can open Kindal on all my devices anywhere and immediately access my huge library in the palm of my hand anytime.
Yep, I have that on my phone and tablet. Have found a lot of good free books to read. I love the public library because the selection is great.
