I also use the heck out of my phone. The GPS alone is almost worth it. I can speak a destination and get voice directions to it. I was traveling and in my rental car, opened the confirmation email I had from my hotel. I touched the address and navigation opened and gave me voice directions to the hotel. I play music on the phone through my car stereo. While doing this I got an important text. The phone stopped the music and read the text to me. I can tether my laptop to the phone if I need to get on line away from a network.
I put off getting a cell phone for years because I didn't want to be bothered by the phone ringing wherever I went. Look, just because the phone rings, doesn't mean I have to answer. Or I just turn it off. Besides, when I discovered that while on the road, I could call the pizza place, and it would be ready by the time I got there...well, that sold me.
The phone is just a tool like any other. It is what you make of it. My phone is a wifi analyzer, flashlight, star identifier, bar code reader, a level, guitar tuner, DJ machine, sound spectrum analyzer....and so forth.
