Microsoft made a big deal out of the fact that apps running in the background take up very little in the way of resources. Great. Well, what if you want to actually quit an app? It’s not so easy. First, you have to press and hold the back button; all the open apps are shown as small panels, and you can scroll to the left or right to choose one. But where Android — and even WebOS — let you close out of an app from this thumbnail view, in Windows Phone 8 you have to open the app, then press the back button again. It’s another extra step we could do without.
