I chose to have a mobile phone and to get rid of my landline simply because the mobile could do more things for less money. However I would switch back to a landline and get rid of the mobile if the converse were true. I can live without one or the other equally well, but in my current life I think I do need to have a phone of some sort. I agree with #3 that there are some serious drawbacks not to mobile phones but to the way people use them.
