"$500 is worth slightly less than the cost of a piece of gum."
First of all, I chew gum.
Second, I will give you the benefit of the doubt and let $500 be worth half a piece of gum.

If I send you $10,000,000,000 you can send me 1 million pieces of gum and keep the change for a tip

I would suspect that $500 is actually worth slightly less than a molecule of air
Btw, how is Windows 7?
