To all the Americans that don't get why the Brits are whining: Apple aren't a charity. We understand that. If you want something you have to pay the price. We understand that.
The issue people have is that the USA Pre-Tax price (displayed on the Apple Website) and the UK Pre-Tax price (found on your receipt or calculated from the website with a simple bit of maths) is different. The Apple TV for example costs £84.17 (+ £16.83 Tax at the new 20% rate) in the UK. At the current rate of 1 GBP = 1.56028 USD that £84.17 is $131.33. However the Apple TV only costs $99 (+ $varying Tax) in the USA. This difference of $32.33 Pre-Tax is what annoys people, and is why some people wrongly thought that Apple might have absorbed the VAT increase in the UK into their profit margin. If Apple had, as some people hoped, reduced the UK Pre-Tax price to £82.50 ($128.72), and thus kept the Inc-Tax price to £99 with the new 20% rate, the UK consumer would have thought how warm and cuddly Apple was at absorbing the VAT rise into their profit margin and overlooked the fact that the Pre-Tax price was $29.72 higher than in the USA.
However as others have pointed out previously Apple's cost of trading in the UK is probably higher than the USA due to both the customers statutory rights and the employees rights....
