eBook readers take it one step further. One device holds about a library and gives you as many of your favorite book titles at your fingertips as you could ever really want. Plus, they make it easy to take notes, save clippings of quotations and highlight passages we want to be able to find again. They’re convenient, portable and good for the environment. In fact, the only real downside we can see to an electronic book over a real paper book is that you’ll have a few more problems if you accidentally spill your coffee on it or get splashed at the pool.
