The latest word from behind Apple-authorized cashiers is that Cupertino has stopped shipping out fresh stock of its entry-level 21-inch iMac. The Core 2 Duo-equipped machines were already looking long in the tooth in this Core i-something era, and so predictably the latest speculation centers around the idea of Apple taking its full iMac range into Core i3, i5 and i7 territory. Nobody really knows any of the specs for the moment, but resellers are apparently being advised to sell through what stock they have and to "keep inventories lean" for the next few weeks. Considering Apple's last all-in-one overhaul coincided with the introduction of the Magic Mouse, we're starting to suspect the company might have another iMac plus touch input device combo coming -- potentially in the very near future.
