Following months of rumors that the new iMac would feature both an LED-backlit display and a Blu-ray player, the truth is out: no to Blu-ray, but yes to LED backlighting technology.

This 2009 refresh of the iMac bumps the display size up from that of its predecessor, and changes the aspect ratio to 16:9, the same one used by most televisions. It also lets you connect external devices like DVD players and video game consoles — a first for the iMac line.

The aesthetic has changed a bit; the front is now class from edge to edge just like the MacBook Pro, and the back is made of aluminum instead of plastic. Yep, it's unibody like all the Apple laptops.

Internal specs have seen a boost: you'll find a 3.06 GHz Intel Core 2 Duo processor, 4 GB of RAM, a 500 GB hard disk drive, a GeForce 9400M GPU, and an SD card slot in the entry-level, $1,199 model. A $1,499 version bumps the storage space up to 1 TB and adds an ATI Radeon HD 4670 discrete GPU for significantly improved 3D graphics performance. You can also put up to 16 GB of RAM in this computer, but obviously that won't be cheap. The screen resolution is 1920 x 1080.

The 21.5-inch iMac is available for purchase right now.
