As many of you know, the new 3G iPhone will come with built-in GPS support.
I purchased a Magellan GPS unit for my sister's husband last Christmas, and I paid nearly $200 for it. It was very impressive. Also, it was the first time I had the opportunity to play with a GPS while not standing around in a Best Buy. The GPS unit is very accurate. Also, the turn-by-turn directions are awesome.
I don't understand why every phone doesn't have this functionality built in. More and more social networking sites are beginning to take advantage of GPS technology as well. It has huge implications on privacy, but for those of you who are big into social networking, it might be a great way to connect with others. It also helps to know where you are in the world. ;)
Personally, if I purchased a 3G iPhone (I might actually do just that), I am thinking that the GPS functionality would be a serious selling point. I do not have a GPS of my own, and I am flat out horrible at remembering directions.
I only wonder if the turn-by-turn directions will be a serious destraction in the car. Does this pose a threat to people on the road? Will this be even worse than talking on the phone and driving one handed? It will be interesting to hear that debate.
Regardless, if you wish to purchase a 3G iPhone, how much does the GPS support influence your decision? Would you use it? Or is it just pointless?
