Aside from refereeing iPad turns between my two kids, the activity I find myself doing most on the iPad is reading newspapers and magazines. Maybe I'm a slow reader or constantly interrupted by said children, but often times I don't finish a page of an article before the iPad dims on me. (Unlike on the iPhone, you can read on the iPad without scrolling every few seconds.) I then have to tap the screen to return to the normal brightness setting. And if I fail to tap the dimmed display in time, the iPad goes dark, forcing me to swipe to unlock the iPad and return to the article I was attempting to read. Thankfully, there is an easy way to prevent the iPad from so rudely interrupting you mid-sentence.
