Lighting is also useful during the daytime when you need to adjust contrast. Rather than using a backlight, most e-readers actually use LEDs mounted along the inner sides of the display that shine light across a thin layer of translucent plastic.

Long story short, this means that you can read in the dark without straining your eyes as you would on a light-emitting screen like your smartphone or tablet.

But if you're really on a tight budget, you can't go wrong with the basic Kindle. The only extra feature here is Wi-Fi, but that's still enough if all you want to do is read ebooks with an E-Ink screen. While you'll never see it in a full multimedia tablet, it's perfect for doing what it's designed to do: let you carry a library around with you that reads like a paper book.
