With the release of iPhone Duo, I found this visualization on reddit. This visualization is helpful when comparing prices of apple products at once through a clear visual hierarchy and the use of visualizations (flags of countries). Hence, this visualization would be helpful for people who are looking into an overall idea of how apple products cost differ without having to look into a complex data analysis. Indeed there are flaws (e.g., sales tax is unclear, conversion rates continue to change, missing currencies and countries), nonetheless, to an average viewer who isn't looking into a deep analysis into prices, I believe this visualization is sufficient and approachable.
