I have an Apple delivery estimate of 25th November which I initially regarded as a "worst case scenario" date but I'm not so sure now. Funny how in the US shipping from Shanghai to ultimate address can be 3-4 days, but here up to two weeks?
Mine, which seems to be in the same slow boat as yours, changed from an estimate of the 26th to the 25th today ... only the APP and the VESA mount have delivery dates listed though - the iMac still just says shipped on 13th November.
