You can buy a PDA with $1400! Or you can eat The Line 20
times!!! Or I can survive on $1400 for 6 months... =X
When I was still receiving pocket money, I would stash money here
and there so that one day when I'm really broke, I will stumble
upon it and suddenly still have money to use. 
Now though I don't do that anymore, I still have a stack of
brand-new dollar notes for use in case my bank account balance
really drops to zero.
