The new iMac features next-generation Intel Core i5 quad-core processors and the fastest graphics ever in an all-in-one computer. It also brings Thunderbolt I/O technology to the desktop for lightning-fast data transfer. And a new FaceTime HD camera lets you make full-screen HD video calls. All from a beautiful, widescreen 21.5-inch LED-backlit display that takes up just a sliver of your desk. It’s everything you want in a desktop. Now more powerful, more advanced, and even more incredible than before.
The iMac’s display offers a 1920 x 1080-pixel resolution (for native 1080p high-definition viewing), and it uses IPS technology to deliver consistent color across an ultra wide 178 degree viewing angle. This 21.5-inch model (MC309LL/A) offers improved graphics with AMD Radeon HD 6750M. Other features include integrated Wireless-N Wi-Fi networking, Bluetooth connectivity, an SD card slot (compatible with SDHC and SDXC cards), one Thunderbolt port, a FireWire 800 port, and a total of four USB 2.0 ports.
