From the New York Times:
"The technology is being seen first in Japan because emergency regulations there require cellphones by next year to have receivers using the satellite-based Global Positioning System to establish their location."

What? What!? Not to sound paranoid, but sometimes there are these little signals that we are headed into a 1984, Brave New World, etc future. So Japan is going to use cellphones as people locaters? That is a scary thought. And it's one of those things you can't really do anything about. If they start doing it in the US, I bet no one's going to say anything about it. Especially if it enables cell phone features like the one the article's about, where you can point your cell phone at a building and it'll tell you what it is.
Example:
Guy 1:"Ooh, ahh, what a cool building. hey friend, look at my cell phone's info on this building."
Guy 2: Does not respond, because a sniper bullet has just hit him in the back of the head.
