Was very nervous doing so but it is done now and I got a very pleasent suprise. I ordered the 20" iMac with an upgraded graphics card which came to £978.
I had seen that today (Friday 1st December) Apple were announcing on this day only at its apple stores. Now it did not day how much the dicount was and the nearest official Apple shop is in manchester so I was not prepared to travel for a discount which might be very small. But to my suprise it seems the dicount counts for buying from the Apple Store online too. They knocked 60 pounds off the price and then if you include vat a good 72 pounds it knocked off.
Result :)
Ordered it to b delivered to mine, but will get a friend with a car to help me take it to my Mum's so I can have it as my main Christmas present.
I am very excited.
When I get it I shall probably update my computer history post I made some time again and post it as a new one. :)
