Buy your iPod in Canada

Perhaps drawing inspiration from the The Economist magazine's annual Big Mac index, which gauges currency valuations and purchasing power, an Australian bank substituted the increasingly ubiquitous iPod for the oft-maligned hamburger.

Canada ranked as the cheapest place to buy a 2 GB version of the device, while Brazil was the most expensive. Surprisingly, Mexico was the fourth cheapest place on the list. An iPod, according to the survey, costs only $5.46 more in Mexico than in the United States.
