The joy of reading digitally is that you can easily drill down deeper into any idea simply by cutting, pasting and searching as you go. Reading a review of a summer movie might have you searching for other films by the same director. An article about the health benefits of blueberries could trigger a search for recipes or even a local grower so you can pick you own.
On a computer, the mouse makes it easy to grab these phrases and go, but that same action is cumbersome on mobile devices. According to Bing, your average cut and paste search takes nine steps, but with their new app upgrade, you can do it in two (sort of).
