@Reyn,
There are Solo plans that start at $10/month. You had to sign a contract - I went with 2 years - mostly so I don't have to think about it for a while. No activation charge etc. No charge for the phone (3G/camera ... all the good stuff). I can add/delete features on a monthly basis.
As I recall it, you get 250 daytime minutes/25o anytime minutes per month. I've used about 45 minutes total since June - about 25 minutes in one sorta emergency call. Most of my calls are less than one minute long.
Hello? Hi Miss X, your car is ready. Awesome, I'll be over to pick it up. Bye. Bye.
Hi. Hi, I'm at the subway. Great, I'll be down to pick you up. See you in a couple of minutes.

I was thinking about this while we were out walking. I don't really use my MP3 player anymore. It was handy while I was commuting by transit, but now I drive - so I don't need a device that contains an MP3 player.
I love my camera and carry it everywhere.
If there was a device that was a fantastic camera, and it happened to have a phone as a not-annoying addition, it'd be the perfect carry-along for me.
