[cercis]

DH and I each have one (plus he has one for work). We have no landline.

I like it because I don't have to be tied to the house waiting for important calls. I can take the kids to the park and just answer the call there. And anymore, all repairmen call about 30 minutes before they will arrive, so if you're waiting for the cable guy (or whatever) you can run out the store or whatever and not worry about missing him.

I also like it because I remember as a kid being sick at school and no one being able to get ahold of my parents, so I had to sit in the office waiting (we didn't have a nurse or infirmary, no bed or anything). This happened multiple times as a kid and I vowed it would never happen to my kids.

Like I said, though, we don't have a landline. So, our costs are probably pretty average.
