My favorite Kindle has a been discounted for Black Friday and I’m buying another

The Kindle is one of my favorite devices: designed just for reading, it’s the perfect example of a bit of tech that’s good for just one thing. Unlike smartphones and tablets that want to do everything, Kindle’s sole focus on reading books is to its credit, making for a great experience. With Black Friday sales now underway, the Kindle Paperwhite – the best Kindle – gets a $20 discount, and I’m going to buy another.
