It'd be smarter to take the money later, but I'm with the group of people who were hit by the economy, and waiting ten years won't help at all. So I'd take the one million.
It's pretty similar buying stocks, you spend money right now, wait for the stock to mature, and gain more later. So if the stock's wroth is gaining a million dollars every year, you would wait for the stock to hit it's peak before selling it.
If you took the million now, you'd get taxed like crazy. 10 million over 10 years wouldn't be taxed as much (if you get a little every week) and in the end, you end up with more.
