The security problems posed by smartphones are obvious and it's so tempting to just ditch it for a dumb phone (or no phone) as you say. Difficulty is that everyone has some must-have application on which they depend. For me it's Google Maps I absolutely need it to get around. If you're in a foreign city and you can't speak the language then Maps will tell you exactly where to find the correct bus or train and show you the route.
