I've got a kindle. It goes where I go. I also have the app on each of my computers and phone. I read so much more now than I ever did.

A lot are indy authors, but I've picked up a lot of really good books for free or almost free. My only complaint is that some of the free books are part of a series. I love the book then I have to buy the series. I have so many books now that I'm pretty selective on which books I download.
