I rely on my Kindle. I don't use it to be trendy or "in". My eyesight is very poor. Even wearing my glasses, which I need every waking moment (I have no memory of not wearing glasses) I get terrible headaches if I read hard cover books for more than an hour. I can't read paperbacks any more. If I can't get it in large print volumes, I HAVE to read it on my Kindle. I have the font set as large as it can go. I can read for as long as I like, with no headaches or eyestrain. It's a blessing for me. Oh, and my prescription is up to date. Sadly, I fully expect sometime in the coming years, to be classed as legally blind.
You should see how large I have my computer display web pages!
