Earlier this month, Apple started pushing back the estimated shipping times for its new line of 21.5-inch and 27-inch iMacs. Apple CEO Tim Cook previously warned prior to the launch of the new lineup that the company expected significant delays leading into the holidays. While the 21.5-inch iMacs are still listed at “7-10 days” on at least Apple’s United States and Canada online stores, the 27-inch model is now listed as shipping in “January”. Apple previously displayed “3-4 weeks”. While we are obviously now only three weeks out until January, the change could mean further delays for the new iMacs and possibly shipments late into January as opposed to at the start of the month.
