PLEASE NOTE: the information below is about the 2011 iMacs - we have reviews of the 2012 model and 2013 model in our blog.

About the iMac

The iMac is Apple's tower-less desktop and the 2011 iMac has two models; a 211/2 inch screen and a 27 inch screen, both with backlit LCD display and 16:9 aspect ratio.

Common to both versions are built-in stereo speakers, 17 Watt amplifiers, a microphone, and Apple's iSight webcam. Connections include a Mini DisplayPort, FireWire 800 port, four USB ports, an SD card slot, digital optical minijack input and output, and a Gigabit Ethernet port.

The slot-loading SuperDrive writes DVDs at up to 8x speed and CDs at up to 24x speed. WiFi and Bluetooth are supported.

The rest of the specification varies according to screen size.

The 211/2" screen supports resolutions up to 1920 x 1080 pixels, but 2560 x 1440 is available on the 27" screen. Both models are capable of powering an external display (up to 2560 x 1600 pixels and 30") whilst still running the built-in screen at maximum resolution.

Both smaller and larger screens are available with dual-core 3.06GHz or 3.33GHz processors, but 2.66GHz or 2.8GHz quad-core options are available on the 27". 4Bg of RAM is standard, upgradable in either 1Gb, 2Gb or 4Gb to a maximum 16Gb. When it comes to disk space, the 211/2" starts at 500Gb, with 1Tb and 2Tb options available; 1Tb is standard on the 27".

When it comes to graphics cards, NVIDIA GeForce and ATI Radeon 256Mb cards are available for 211/2" screen; you can upgrade to 512Mb on either the dual or quad core processors on the 27" version.

The 27" screen can also be wall mounted, and will accept external input from DisplayPort compatible sources.
