I read primarily on a kindle and it's awesome! You can borrow from your library system and get a Kindle Unlimited subscription which works as a $10/month library. There are tons of free book promotions. Or you can buy ebooks if you really enjoy them.

It saves me a lot of money, especially because I live too far from my local library to utilize it properly (24 miles away is not convenient or a reasonable use of gasoline and time).
