I use my phone mainly as a pocket watch; also it has a token generator thing on it which I need for work. The map app is sometimes useful, though I've never been very good at relating the map to the streets around me. I have a couple of news apps, for reading while commuting (not something I do much of ATM).

The key to successful phone usage is, when you get a new phone, don't tell anyone beyond your immediate emergency contact individual your new phone number.
