Sony Playstation 2: Export Restrictions from Japan
A CNet news article reports Military analysts cited the example of a Tomahawk missile that needs to ``see'' where it is going until it strikes its target and must process graphic material at high speed to keep to its target. PlayStation 2's graphic processing capability is fast enough to enable it to be used in a missile.
Just another example of the law being behind the times. The PS2 is supposed to be quite a jump forward... I'm guessing it'll be quite some time before our Macs can properly emulate a PS2. :)
