I once wanted to go to outback and ended up at someones house. Other than that the GPS is great. Id does more good than harm. The only problem I have is that that more I use it the more dependent i become on it. Before, I would remember how to get to a place the second time since I had to put an effort to remember it. Now i don't really pay attention where i am going I just follow the instructions.
Lets just hope that this blind following is not the start of computer's plans to take over mankind...
