The iMac's form factor was last updated in 2009 with its unibody 21.5-inch and 27-inch displays. Today, Apple is updating the iMac again, not only with the latest hardware, it's also incredibly thin.
Like the MacBook Air and the Retina MacBook Pro, the iMac eschews the optical drive.
Still, don't think the new iMac is low on specs. The devices can be configured with quad-core i5 or i7 Ivy Bridge processors and can take up to 32GB of RAM.
The Ivy Bridge means users have access to USB 3. Users will be able to choose between a traditional hard drive, an SSD or Apple's new Fusion Drive.
Fusion Drive is Apple technology that allows users to have a hybrid SSD/traditional HD experience. This means that you're most used and disk-intensive apps load from the SSD but your media, movies and music can still exist on a traditional hard drive.
The 21.5-inch iMac will start at $1429. It'll have a 2.7 quad-core i5 with 8GB of RAM and a 1TB hard drive.
The 27-inch iMac will start at $1999 for a quad core i5 with 8GB of RAM and a 1TB hard drive.
You can upgrade the 21.5-inch or 27-inch iMac to use either an SSD or Apple's new Fusion Drive.
The 21.5-inch iMac will go on sale in November and the 27-inch model in December.
