Should I get an iPhone?

I think maybe I need an iPhone. I think perhaps I’m the only person in my world who does not have one. I use a mobile phone with actual buttons that you press, and never use any of the special features. It lives in my handbag or on my kitchen bench or on the desk I used most recently. I don’t like carrying it in my pocket, and sometimes I take a couple of days to check for my messages, which can be bad. My mother always taught me not to let my life be run by the telephone, and this has slipped into the way I don’t use my mobile. 

But everyone seems to have an iPhone. Maybe it could replace my still camera, my video camera, my iPod nano, and my land line.  I worry about data charges getting out of control, and becoming addicted to checking emails or Twitter everywhere I go. But I’d love to have something on me that’s not too obtrusive to capture the kids when they do something cute or crazy. 

Do you have one? Should I get one? My neighbour said her iPhone changed her life. Did it change yours? Would it change mine?
