What will this decade be remembered for?

[poltr1]

It's getting close to the end of the 2000s, the '00s, or whatever you want to call this decade. When we look back on this decade 20 years from now -- nostalgia usually looks back 20 years -- what items and fads will we remember and instantly think, "Oh, this decade!"

The only thing I can think of right now are those magnetic ribbons that people put on cars. There's got to be others.
