Replacement screen
I got the 'phone call as I had previously 'phoned AppleCare and complained about the screen (actually it's not THAT bad - slight yellowing in the bottom RH side only), and that TechToolPro had diagnosed a SMART fault with the HD, even though TechTool Deluxe and, later, on the advice of Applecare, the Apple Hardware test, found no fault with the SMART status.
Has anyone else found the same problem?
The Irish guy (after commiserating about the Rugby performance over the w/end) stated that 1) the 7 days was an absolute max - it should be shorter than this, and, 2) that Apple's preferred option was for me and others to take it to their local Apple store rather than parcel it back to them. The reason given was that this meant I could fire up the machine in-store and check that all was well. (To a pessimist this would sound as if Apple weren't completely certain that this fix was going to work... but I'm going to trust them...)
