That's not that delayed. A few weeks isn't out of the ordinary, they may just have more demand than expected. Compared to the car industry and others that use older, far more constrained chips, this is nothing.Not correct. The iMac is still on delayed shipping. Order today for delivery in September. That's the base model. All the others are for late August shipping if you don't do CTO. Increase the ram and delivery is for September.
EDIT: I just checked and I can get one by the 18th at the earliest, with Sept 9th being the very latest I could get it to go. Delayed for Apple but in the grand scheme of things that's not bad at all.
