a green one-dollar bill but that was replaced by the golden loony coin years ago.

Speaking of money, not that I want to divert the thread so much, but why is it that the rest of the world is content with using a on-dollar (or equivalent) coin, but people in the US refuse to and simply hoard them as collectors items? It's the same with the metric system, 24-hour clocks and evolution. What is it with the US mindset that makes us at once so technologically advanced and stubbornly stuck in our ways?

I, for one, loved using the 1- and 2-pound coins while visiting England. It's just seems so convienient, yet I don't think I've seen more than one one-dollar coin in the last year.
