I know I've told these stories in another thread, But it bears repeating.
The uses discussed here are some good ones.These devices also, however, bring great amusement to me. My 26 year old niece has lived in this area all her life and has had one for years. She has been to my home countless times, but when her GPS failed last year, she had to call for directions!!! It's not like she got lost, she called from her home. Her father is not much better, but does seem to be able to get around without one. Although he did have to buy a $1000.00 one!
I can see having one if you take a lot of trips. I've wanted the marine version for a while. Not to know where I am, but more for knowing the water depth where I am.
