Do you still use a landline at home, or do you rely completely on your cell phone?
I have a landline at home, and don't actually own a cell phone (other than the one that I have for work, at work, but which I don't take home with me). Ever since I switched the home internet connection to high-speed, the landline phone is always open, as opposed to when I was on dial-up.
Personally, I don't really want a cell phone. While I see a use for it in emergency situations or when one is out for long periods of time, I would find it irritating for folks to be able to get hold of me anywhere or wherever I am. I know I find the damn things annoying in social places and situations, and some people just still do not get the concept of cell phone etiquette. I had an experience with this at CanGames, during one of the games I was running, when a player in the middle of the action got a cell phone call. Anyway, enough ranting and rambling about this...
