I sell products around the world and last year has been great b/c a weak dollar means we sell more overseas. It took a long time for the dollar to decline, but in a very short amount of time, the US dollar has gotten much stronger. This is the one year graph of the Australian dollar:

What it means in real world terms is that inflation is no longer a problem for us since what we import is now cheaper. Its bad news if you work somewhere that exports overseas, but day to day it is actually a good thing. The crap you buy at wal-mart is going to get cheaper or at least stay the same price.
And since inflation is no longer a problem, the feds can cut interest rates to near zero which will get people borrowing money again. In theory anyway.
