Sorry if this has been noted before or if i am incorrect, but I just noticed that the 1 Terrabyte Harddrive option for the iMac appears to have dropped (about £100?). I have been eyeing up a 2.8 24" for a while with 750gb or 1tb harddrive, and i am sure it was about +£190 to go from 750gb to 1tb, which i thought was a ridiculas jump so was gonna settle for the 750gb. But on the site today it shows as +£91. Has it changed or am I losing it??
