The basic premise is the same: an amazingly clear, bright and vivid IPS LCD display – either 27-inches running at 2560 x 1440 resolution, like our review unit, or 21.5-inches running at 1920 x 1080, slotted behind a sheet of glossy glass and then into a minimalist aluminum chassis. Ports are neatly lined on the lower left hand corner of the rear panel, with only a slot-loading 8x SuperDrive dual-layer DVD burner spoiling the sides. The whole thing is lifted by a neat stand – complete with a cable-guide hole – with 17W speakers along the bottom edge and an integrated microphone. New to this generation is the FaceTime HD camera, more on which in a moment.

Ports are broadly the same as before, so you get audio in/out, four USB 2.0, a FireWire 800, two 10Gbps Thunderbolt ports on the 27-inch iMac (just the one on the 21.5-inch version) and gigabit ethernet. There’s also WiFi a/b/g/n and Bluetooth 2.1+EDR, an infra-red port for use with Apple’s media remote (sold separately), and an Apple Wireless Keyboard as standard; this time around, iMac buyers can pick between the Magic Mouse or the Magic Trackpad.
