I like cell phones because they're a measure of safety for me. If I'm in an accident, have a flat, or whatever I can easily summon help. Also, if I'm at the store and forget something I can call home and check it out. Yesterday, I picked the youngest up at her friend's house to take her to the stables. We were traveling on some unknown roads. The map printed out wasn't specific and I took a wrong turn. I called hubby and he pulled up the map on the internet and was able to redirect me back to where I needed to be. Many minutes were saved by that.
I have used our phone when I've been lost too -- just 2 months ago I got so lost in another state that I was nearly in tears. I just don't get the people who have them stuck to their ears the entire time they shop at the grocery store, etc.
