I just got off the phone with my 79 year old grandmother who just can't understand that I do not have or want a landline. Every two or three months she asks me for my "home phone number" and I have to explain to her that I don't have one and don't need one. I tried to explain Skype to her and she just couldn't understand the idea of talking on the phone through a computer.
I started thinking about it, and I can't think of any of my friends who are anywhere near my age who have a landline. It almost makes me wonder if in a few years/generations landlines are going to be a thing of the past.
My mother (56) couldn't figure out how to use my iPhone. She asked to use it and I pulled up the keypad for her to be able to dial. I checked back a couple minutes later and she was looking at it, taking off the cover, and trying to find the keypad, hehe.

So what about other people? Do you have a landline, cell phone (mobile

) or both?
