My sister has Parkinson's and she appreciates that can turn pages with just the press of a button. Also, you can choose the size of the print. Hers is a Kindle.
I received a Nook for Christmas. It is a basic model and I am still learning about it. One of the good things is you can go to the Barnes & Noble for free instructions. Also you can go there and read some for free. We have a store within two miles of us so it is very convenient. I really don't know very much about the process yet. I really think it will be good for vacation reading.
I still get books from the library.
