If you ordered a 27-inch iMac shortly after they were announced, you may be getting it soon. According to “MacRumors” (www.macrumors.com), the all-in-ones are “Preparing for Shipments” for early buyers.
Alas, if you didn’t order early, you’ll have to wait a bit. Shipping estimates for new orders placed for the newest generation of new 27-inch iMac models have slipped from “3-4 weeks” to “January,” per the Apple online store.
