Love them or hate them?
Put me in the hater category. I had one, for emergencies and for contacting home when I needed a pickup at the train station. Or to ask if we needed anything at the grocery store, etc.
But I hated that people assumed that because I had a mobile, they should call me on it instead of at home. I'd never hear it, for one thing, since my handbag was always in a closet somewhere. Plus when I'm out, I do not want to talk to you unless you are asking when you should pick me up at the train station. Or warning me to avoid the M25 because it's full of parked cars.
When I worked on campaigns, I used a cell phone or two, and I could see the usefulness of it. But having to use a cell is one aspect of working life I am happy to give up. I really hate that annoying beep that tells you someone called, or that you have a message. And I can't text for shit.
While we're on the subject, I don't especially like voice mail either, though I love caller ID (but don't currently have it, damn BT!). I also never use a phone book.
Oh, and get off my lawn.
