The results are far-ranging, and obviously subject to Apple's local pricing policies in addition to government and trade restrictions. Worst places to shop for a Nano: Brazil is by far the most expensive at $327.71, way more than 2nd through 5th places India, Sweden, Denmark and Belgium (all under $225). US shoppers have a pretty good deal at the list price of $149, with only Japan, Canada and Hong Kong slightly cheaper. See the MR post as well as the Yahoo News story for more analysis of the macroeconomic implications of the tiny MP3 player's price tag.
It's amazing that in only five years the iPod has achieved enough global brand status to allow "indexing" alongside the Big Mac, Coca-Cola and a Starbucks latte.
Update: Headline corrected to "Nano."
