I have family and friends in other cities and a girlfriend across town. Texts are just too convenient not to have when you need to coordinate. Just last week a friend passed through town looking for a new car and we met up for dinner - never would have happened without a phone. GF gets into a minor accident (not her fault, she would like to point out) and I can be over there in minutes thanks to a couple of texts. Father breaks his knee and I can follow how he's doing in real time, rather than finding out at the next family gathering.

I could do without the "smart" part of the phone. I really just need texting/calling (mainly texting). But I don't want a land line, and I'm pretty sure my relationships with friends and family would quickly deteriorate without my cell phone.
