Apple has today upgraded its range of MacBooks with Intel Core 2 Duo processors, the upgraded configurations are immediately available across all sales channels.

The new chips mean the latest MacBooks are "up to 25 per cent faster" than the preceeding generation, the company claims.

They continue to offer all the features that made first-gen models so attractive, including built-in iSight cameras, the MagSafe power adaptor and iLife '06.

"MacBook has helped drive Apple's notebook market share to over 10 per cent in US retail, and the new MacBooks will be among this holiday season's most exciting new products," said Phil Schiller, Apple's senior vice president of Worldwide Product Marketing.

Prices remain more or less the same, the entry-level model costs £749, while the mid-range price has fallen slightly, to £879 (from £899) and the most expensive black model has seen its premium on colour fall £30 to £999, with a hard drive that's 40GB larger than that of the mid-range model it is otherwise identical to.

The range includes three models: white 1.83GHz and 2.0GHz MacBooks and the 2.0GHz black model.

Apple has at last beefed up the amount of memory it ships as standard in these Macs, with 1GB of memory shipping as standard in all models bar the entry-level configuration, which still ships with 512MB.

The included SuperDrive (available in the mid-range and black model) has also been souped up, a double-layer optical drive now shipping as standard. (Entry-level offers a combo drive).

MacBooks also feature glossy screens, Apple's Sudden Motion Sensor, Scrolling TrackPad, built-in AirPort Extreme and Bluetooth 2.0+EDR networking, 10/100/1000 BASE-T Gigabit Ethernet, two USB 2.0 ports, a FireWire 400 port, combination analogue and optical digital audio input and output ports and a mini-DVI video output to connect up to a 23-inch Apple Cinema HD Display.
