OK then let's play the numbers game.
When the last revision was released in April last year, the exchange rate was £1 -> $2.
The base model for last revision was about £680 with VAT removed (17.5% back then). The iMac started at $1199.
£680 x 2 = $1360.
Now I expect rip-off Britain to add a fair bit on top of the US price, but it doesn't change the fact that last year, they were raking in roughly an extra $160 per low-end iMac sold. It was the same story across the line. Like the high-end model which cost $1,799.
£1,190 x 2 = $2,380.
Now if Apple made all that extra juicy profit last year, why can't they take a temporary hit? I'm not saying that I'm completely opposed to a price increase in the UK, but by the margin Apple has done it is plain ridiculous.
Oh and remember, people in the UK don't earn money relative to US dollars. £1 earned is still £1. So relative to the UK salary, the iMac has increased significantly.
P.S. The price of the baseline iMac before the update was £782 (15% VAT) so still £680 before VAT, not £652 as stated in the first post.
