I use it before I sleep, because I start to read and fall asleep. And in the mornings, it's my alarm.
Hey, there's this great invention you might not have heard of before, but they're called books. They're these things that are full of words on paper called pages. You can hold them, you can turn them, you can feel the paper on your hands when you read them, you can bring the book whereever you go and not have to worry about a battery dying or even look at a flashing screen. Plus, you don't need to constantly change the size of the text or zoom in on pictures (if you read a comic) as everything is right there at your fingertips. Oh, and you can also set the book on your shelf next to your others and have them all on display.
