The current Mac prices in the UK were set with the exchange rate in the $1.40-$1.45 range. So it's not too difficult to work out how they might be adjusted on Thursday/Friday. At minimum you should probably expect a 15% price increase on current prices, but I think they may raise prices by as much as 20% in the UK. Apple will want to insulate themselves against further GBP depreciation that most analysts are forecasting.
