In the last few years, e-readers have gone from novelty items to must-haves for many book lovers and casual readers alike.
One of the most popular e-readers is Amazon's Kindle, and one of the most popular places to buy books is from Amazon. Of course, not everyone wants to drop money on an e-reader when they already have a computer, smartphone and/or tablet.
That's fine because you don't actually need a Kindle to read e-books. Just load up the Kindle app on your smartphone or tablet and the entire Amazon e-book marketplace is available.
What's even better is that you can load the app on multiple gadgets. So when you switch from a tablet to a desktop, or your Kindle to a smartphone, you never lose your place. The Kindle app even transfers annotations and highlights you've made.
