Steve, I'm not a texter either. Seems like a waste of time to try to type a message when it'd take less time to just call the person up and talk. But I do use a lot of other things it can do.
Living in LA, one of the handiest apps I have is one that shows real-time traffic conditions on the freeways and highways. Or last weekend in Palm Springs I wanted to find a good steak dinner, and a bar with pool tables for some after-dinner recreation. Between Google and Yelp, I was able to find both very easily.
When I was setting up my booth at the park, I needed to put blocks of wood under some of the table legs to level them and to make sure my shelves were level. I have two or three different "bubble level" apps on my phone to choose from, so I used my phone to level the tables and shelves.

You guessed it...iPhone.
