Despite its large 27in. 2,560-by-1,440-pixel LED-backlit display, the iMac's hinge mechanism works beautifully: you can tilt it with a light push of the finger, and it stays put when you let go. This iMac isn't small, measuring 51.7cm high by 65cm wide by 20.7cm deep and weighing 13.8kg, but it looks and feels elegant. The two openings on the side are for a slot-loading optical drive (8x SuperDrive) and an SDXC flash card reader.
The 27in. iMac's aluminium back panel looks striking, but it can become quite hot after prolonged use of graphics-heavy applications.
Connections at the back comprise a pair of audio jacks, four USB 2.0 ports, a FireWire 800 port, a Mini DisplayPort and an Ethernet (RJ-45) port. Wireless connections are Wi-Fi (802.11a/b/g/n) and Bluetooth (2.1+EDR). You'll need to pay extra for adapters if you want to connect external displays via DVI (£25), VGA (£16) or dual-link DVI (£69).
