Anyone know of any GPS cards for Mac laptops such as powerbooks? I know there are compatible devices but are there any of those cool GPS CARDS for Mac? Also, I'm kinda freakin out over Big Brother watching everyone. People buy those portable GPS devices to be rescued if something happens to them. That must mean that the government has the ability to find your exact coordinates if you have one of them. Are GPS cards for laptops just like this? Can anybody track you down when you have an active card installed? That opens another discussion on GPS in cars. Would you really like to have fun with the car telling you where to go when the government also knows where you're going? Ya so, if anyone can answer one of my many questions, reply.
