I'm interested in picking up a 21.5" 4K iMac, either the mid or high end model, but it seems all the Apple stores within driving distance (about 8) are all sold out of both those models. On top of the no stock, Apple has the estimated shipping dates for both 4k 21.5 model's set to late January or early Feb! Why so far out?? Is this just a combination of Covid and Christmas, or is there another reason the 21.5 4k is out of stock everywhere? Are they releasing an M1 version soon? Even all the best buy stores within driving distance are sold out of the 4k 21.5 models. Apple is usually pretty good at keeping stock in stores so I'm surprised to be seeing this, especially with shipping dates pushed back to late Jan early Feb seems unusual.
