I only use my mobile for urgent calls, eg to my wife that I will be late

because of a business meeting; stuck in traffic (dating someone from the

office!). Or if I am staying away from home and want to contact
someone (hotel phones are even more expensive!). The only calls I get

is someone who wants to contact me urgently.

 building, I don't

receive a decent signal on the mobile. The office landline works
perefectly well.

I really don't want to watch tv/surf the web on a small screen.

Ditto, I rarely even take my mobile out with me or even turn it on. I only give my number to a very few select people.

At home I tend to use IM for contacting people. I personally
find the telephone one of the most annoying inventions ever
and would advocate the death penalty for those that use mobile phones
in public.
