Dan Moren, Six Colors:
However, as the dust of the event cleared, the existing 27-inch iMac was nowhere to be found: it’s no longer displayed on the Mac section, nor is it obviously available for purchase on Apple’s website. Putting it in the Compare tool shows no price, nor Buy button.
The M1 iMac continues to be branded the “iMac 24″” which seems to leave the door open for a different-sized model. That suggests to me that a hypothetical 27-inch would be viewed more like a size variant and have more in common with the 24-inch model, treating today’s announcement of the Mac Studio as the heir to the iMac Pro role in the line — display, keyboard, and mouse sold separately.
