For the second time, Apple has pushed back delivery of new 27-inch iMac models to 3-4 weeks, signalling further wait times for customers who order the larger of the two new iMac models. The 21.5-inch models are still somewhat constrained, but continue to list 7-10 business day ship times. Apple had previously warned that 27-inch models would be in very short supply, but expected demand to ease after the holiday shopping period.
