Border fraud. Nice.
It's no different from moving house to another country and taking my 1 year old laptop with me...doesn't matter if it's been open in country A for 5 seconds or 5 years before moving to country B.
It's not Apple's fault that your country charges excessive tax. They shouldn't have to take a profit hit because of it, so comparing prices without tax to a price with VAT included remains disingenuous.
VAT in the UK is 20%. The price difference is like 30-40%.
US price is still about 18% cheaper than UK price pre-tax.
I don't understand why you are revolving your comments around VAT, what I am trying to say is there is obviously something else there.
