The only person I know who doesn't have a mobile phone would be my Italian teacher.
I have a mobile phone but I basically only use it to listen to music and maybe as a camera. I rarely use it to text (ugh I hate texting. Typing's so much easier anyway) or call anyone (for that I'd just use land line), and I really can't understand the people who spend most of their time with MSN in front of them and a mobile in their hand constantly sending and receiving text messages/calls.
Hell, I can't count the many times I was talking to a friend and suddenly their mobile phone rings, soon followed by the familiar 'sorry, hold on a sec'.
My mobile phone, despite having it for over a year now, is still in mint condition O.o.
