Apple often touts the design of its products alone as a reason to buy them, and it's clear that the company spends large sums of money on industrial design. In the case of the upgraded MacBook Air 13-inch, however, it's clear that they've not done a lot of tinkering compared to. You could put the two side by side, and, unless you looked carefully, you wouldn't spot the differences between the two models.
One of the key differences is a feature that was found on the original, much more expensive, MacBook Air, as a backlit keyboard is now standard. It was a feature that we notably missed from last year's model, although if the glowing keys annoy you, it's quite easy to dial it down or switch it off completely.
Like its predecessor, the MacBook Air is quite thin — 30mm at its thinnest point — and at 1.35kg, it's quite light for a 13-inch notebook. There's a trade-off in that slender profile; you don't get a lot of space for ports. All you'll find around the body of the 13-inch MacBook Air are two USB 2.0 ports, a headphone socket, a magsafe power connector, an SD card reader and a lone Thunderbolt port. Compared to the port offerings in competing 13-inch notebooks, the MacBook Air looks a little, well ... thin, if you'll pardon the pun.
We tested the entry-level MacBook Air, which currently retails from AU$1449. Our model was the stock option MacBook Air without any upgrades, which means that it sported an Intel "Sandy Bridge" Core i5-2467M 1.7GHz processor, 4GB of 1333MHz DDR3 RAM and 128GB of on-board storage. One key switch that the new MacBook Air has over its predecessor is that Apple has dropped the Nvidia GeForce 320M graphics processor in favour of Intel's integrated HD Graphics 3000 processor with 384MB of on-board memory. The 13-inch model differs from the smaller 11-inch model in the area of screen resolution; where the 11-inch model has a native 16:9 1366x768-pixel display, the 13-inch sports a 16:10 1440x900-pixel screen.
The MacBook Air runs Apple's latest iteration of OS X, otherwise known as "Lion". We won't reinvent the wheel; you can read our full review of Lion here, bearing in mind that you don't have to worry about the installation steps when first unpacking the MacBook Air.
Where Lion gets interesting, in the context of the MacBook Air, is in how Apple provides the operating system. Last year's Air shipped with Snow Leopard on a wafer-thin USB drive, but the new MacBook Air omits this. Instead, it comes with a recovery partition that you can reinstall the operating system from, as well as the option for Internet Recovery. Internet Recovery is built into the MacBook Air (and the new Mac Mini) EFI, allowing you to download the entire operating system and application suite pre-installed onto the Air, directly from Apple's servers. That would be a slow way to reinstall the operating system from most Australian broadband connections; we'd suggest that most Air users should re-download Lion itself and set up a boot USB drive for recovery purposes.
There are all sorts of ways to test the performance of a laptop, and with Apple being somewhat late to the game with the MacBook Air in terms of Sandy Bridge processors, we were keen to see how the Air stacked up against other Windows notebooks. One of the first things we did was to install Windows 7 Ultimate Edition via Boot Camp. That's still relying on Apple's downloaded Windows drivers, which, in the past, haven't been all that flash.
For a system with these kinds of specifications, we'd expect PCMark05 figures in the 6000-7000 range, and 3DMark06 figures around the 3000-3500 range. The MacBook Air sailed past those expectations quite handily. Its 3DMark06 score of 4245 isn't going to offer superb gaming performance, but it certainly shows that the hardware is working hard. On the productivity side, the Air excelled, with a score of 9293, above what we'd expect to see from this particular processor. Clearly, the use of an integrated SSD pays dividends in productivity terms.
