Apple today has updated their existing iMac lineup by dumping Core 2 Duo altogether and bringing Intel’s Core i3, i5 and i7, along with faster graphics card options. Available in both 21.5 and 27 inches, the prices of both the entry level base model, and the flagship model remains same as the older ones, except that these new ones have more power then ever before.

Here’s some interesting news related to iMac and iOS 4. How many of you thought that iOS 4 is limited to the iPhone, iPod touch and iPad only? We used to think the same, but looks like all that’s going to change. Apple is planning to ship iOS with its next iMac refresh with a touch-screen display.

Sources at Macworld Australia are reporting on a new SKU, which is currently on its way to Australia containing thousands of new Apple stock inventory with the product number MC516LL/A K87 BETTER BTR-USA. But they aren’t quite sure what it is? They’re assuming it to be an updated version of MacBook Air.
