We used to swap discs on our PS2 playing FF 7, 8, 9 etc because that was lik what....10 years ago. Now its nearly 2010, and only the Xbots will defend their machine saying that there's nothing wrong with swapping 1 billion discs.
So yeah, men used to travel using a horse and cart...now we travel via cars/trains etc. We can go back to the olden days and travel via horse and cart, but who wants to?
