GPS is very useful tool in these days. almost 10year ago, navigation system was invented and used to find out every place. but there are some bad effect for using GPS. a few month ago, it was a problem about collecting private information from smart phone. so bad effect is that abuse this kind of information. if government or company get this information, they can pursue a person's activity and also can know where someone moves. for instance, Gaddafi was detected where he hide because he was used his phone. it's a good effect for using GPS. but if someone uses a bad way. it'll be bad for private life.
except this ways, it has lots of good effect. for example, most of people have smart phone. and we can use smart phone. when we go to some place at first time, we can use map service from smart phone. we can search a name of building or place. we also find to some thing around of me. that's good way.
so I agree to use GPS.
I agree with your opinion.
