I can think of a few situations. You're in a meeting and your phone buzzes. You can quickly read the message without being rude, where typing a response would be considered rude (at least in my office). I'll often do this to make sure it isn't something important that needs immediate attention. This also applies to driving. It would be unsafe to type a response, but reading a message in my opinion is fine. Similar to glacing at a GPS.
