I'm really interested in switching from my PC to the new iMac. But why is it that prices on the UK Apple website are more expensive than the US one? I thought i read that when one of the products is updated the prices will be updated too with the current exchange rate? I would like to get the 24 inch, 3.06GHz model, which costs £1,389.00. On the US website the price is $2,199.00, which using http://www.x-rates.com/calculator.html comes out as £1,104.58. So why does it cost an extra £285 in the uk?
