We’ve known for a while that Apple (AAPL) has had trouble producing enough of its new 27-inch iMacs to meet demand, and now it seems that the shipment date for the super-slim desktop computers has been pushed back to February. 9to5Mac notes that the Apple’s ship times for the new 27-inch iMacs now stand at “three to four weeks,” which means that anyone who orders one of the new computers probably won’t get it until February at the earliest. The good news for iMac fans, however, is that the 21.5-inch models are still slated to ship over the next seven to ten days, so people who order the smaller iMac should still get it by the end of the month.
