Shipping estimates for new orders of the 21.5-inch and 27-inch iMac dramatically improved today, with both models now shipping in 1-3 days from the online Apple Stores in Canada and the United States.
During Apple's first quarter financial call, Tim Cook noted that iMac supply constraints in the fourth quarter had impacted sales results. He expected supplies to increase during Q1 2013, which was confirmed in late January with a report that assembly rates for the iMac had been improved.
Apple's redesigned iMac is considerably thinner than its predecessor, with 40 percent less volume and a 5mm edge. The newly implemented lamination process provides improved optical quality and an anti-reflective coating.
Update: As noted by MacRumors forum members, changing the base configuration of the iMac results in a shipping time of 2-3 weeks.
