I don't control the prices, heck I don't work for MS.....but I know that each area/country has a local Microsoft Subsidiary that sets local prices based on the local market conditions. Another example, in Europe many of the Technology Prices in Euros are the same price in dollars, I've seen ATOM Tablets for 300 Euro that cost $300 USD, but that makes the European Price 60% higher....
Things seem to pricier in Europe, and of course our friends down under spend even more on their technology....
