The latest versions of the MacBook , MacBook Pro and MacBook Air are the kind of kit you'd happily swap your kidneys for. But which one should you go for, and much kidney would you need to sell? Here's everything you need to know about the MacBook range: specs, prices and how much it'll cost to replace those internal batteries. MacBook vs MacBook Pro vs MacBook Air: Price Entry to the MacBook family starts at £867 for both the MacBook and MacBook Air, with the 2011 MacBook Pro starting at £999 - although of course if you head for the top of the range and start adding custom options you can easily make a Mac that costs more than a car. There's only one MacBook, but there are two base MacBook Air models - an 11-inch for £867 and a 13-inch for £1,122 - and three MacBook Pros: a 13-inch (£999), a 15-inch (£1,549) and a 17-inch (£2,099). MacBook vs MacBook Pro vs MacBook Air: Processors The MacBook and MacBook Airs have Intel Core 2 Duo processors: 2.4GHz on the MacBook, 1.4GHz/1.6GHz on the 11-inch MacBook Air and 1.86GHz/2.13GHz on the 13-inch MacBook Air. The MacBook Air's solid state drives more than compensate for the comparatively slower processors: they have a dramatic effect on performance, making the Airs genuine flying machines. The entry level MacBook Pro has a dual-core 2.3GHz Intel Core i5, with a dual-core Core i7 in the 2.7GHz model. The 15-inch and 17-inch Pros have quad-core Core i7 processors: 2.0GHz, 2.2GHz or 2.3GHz in the 15-inch and 2.2GHz or 2.3GHz in the 17-inch.
