MacBook Pro: UK vs US Prices

Having lived in the UK a long time, I appreciate that prices are higher over on this side of the pond. Nothing seems to have changed with the release of the MacBook Pro.

Looking at the US and UK Apple stores:

UK Apple Store

1.83 Ghz Intel Core Duo - £1,429 ($2,505)
2.0 Ghz Intel Core Duo - £1,779 ($3,118)

US Apple Store

1.83 Ghz Intel Core Duo - $1,999 (£1,140)
2.0 Ghz Intel Core Duo - $2,499 (£1,425)

I have used OANDA.com for the currency conversion where the rate was - £1/$1.753)

Apparently it is all to do with volume. Apple don't plan on selling as many units over here, hence the difference in price.
