Apple has launched the latest generation of iMac. Available in 21.5-inch and 27-inch models, the all-new Apple iMac measures at just 5mm thin at the edges and is 40% smaller by volume than its predecessors. It supports up to 2560 x 1440 pixel resolution, quad-core Intel Core i5 processors, up to 32GB of RAM and a FaceTime HD 720p camera. The new iMac can be configured with the new Fusion Drive storage option that combines a 128GB of flash memory with a 1TB or a 3TB hard drive. The 21.5-inch model will be released in November 2012, while the 27-inch model will be launched in December 2012.
