Australia's Commonwealth Bank, inspired by The Economist's "big mac index" has created an iPod index(http://biz.yahoo.com/rb/070118/ipod_currencies.html?.v=1) to try to show how various countries' currencies are really valued against each other. They chose the 4 GB nano to compare. Brazil comes in at #1 with a nano costing over $300, and Canada is the cheapest place in the world to buy said nano.
