Here it is, the thinner new iMac — and it is extremely thin. Apple's using a ridiculously aggressive rounded backplate to make the sides appear almost impossibly thin until you come around fully to the back, at which point the true depth of the machine is apparent. It's a trick, but it works incredibly well, especially on the 27-inch model.

Although Apple isn't calling this panel a "Retina Display," the techniques and appearance of this panel are pretty close to Retina-level: the laminated front glass and anti-glare treatments make images look like they're lying right on top of the screen, and the same scaling options you get on a Retina MacBook Pro are present in system preferences. (The highest available resolution on the 27-inch model is 2560 x 1440.) Overall it looks stunning — the first real reason to replace an iMac in years.
