2011 has seen Intel's new Sandy Bridge processors and chipsets creeping slowly into every machine in Apple's lineup - we saw it in the MacBook Pros in February (see our review) and more recently in the new iMacs (we also reviewed those). Now that Lion is out (you guessed it, we reviewed that too!), it’s time for the rest of the lineup to get with the times.



The next product in Apple's portfolio to get Sandy Bridged is the MacBook Air, which was last refreshed in October of 2010. That refresh saw the Air line achieve the original model's potential in many ways, with a more affordable 11" model bringing it within reach to the common man and standard SSDs across the line removing the bottleneck of the first model's 1.8-inch 4200rpm mechanical hard drive. It should also be noted that things seen as deficiencies in the original Air (like, say, the absence of wired Ethernet and an optical drive) are becoming less inconvenient as time goes on, since ubiquitous wi-fi and easy-to-download software are making these missing features less essential even in workaday Windows laptops.

As usual, I'll give you the hard facts first, and get into details and analysis after:

As with the 13" MacBook Pro, the Air's Sandy Bridge bump jettisons the Core 2 Duo processors and the nVidia chipsets that have accompanied them since the unibody MacBooks were introduced in late 2008 (in fact, the only nVidia chips to be found in Apple's products at present are in the still-unrefreshed MacBook).

Thunderbolt also comes along for the ride - for those of you just tuning in, Thunderbolt is an Intel-developed port that replaces the previous Mini DisplayPort while maintaining compatibility with previous-gen Mini DisplayPort dongles (read more about ThunderBolt here). Thunderbolt has the potential to be more useful in the Air than in any of Apple’s other offerings – the Air’s size makes it difficult to upgrade, but a high-speed external port (with the ability to drive multiple daisy-chained displays) makes expandability less about the laptop’s ports (or relative lack thereof), assuming you can find and pay for Thunderbolt devices to suit your needs.

Without a model in-hand, I can’t give you any benchmarks, but expect the performance bump to be similar to the 13” MacBook Pro from earlier this year: CPU speed is going to get a much-needed and very noticeable bump, while graphics performance will remain just about the same as in the previous model. Especially in the 11” Air, however, keep in mind that a 1.4 or 1.6 GHz Core 2 Duo may have bottlenecked the GPU in some cases, so the increased CPU speed may actually result in better framerates for the new models.

The new models also get some spec bumps that make them more suited for use as primary machines: RAM is bumped to 4GB on all models except the low-end 11" (which is upgradeable to 4GB for $100). The “high-end” version of each model gets a CPU speed bump option (a 1.8GHz i5, in both cases, for $150 in the 11" and $100 in the 13"), and the high-end 11" model has a  256GB SSD option for $300 (otherwise, SSD configurations are the same as the 2010 models - I would have liked to see the 64GB SSD phased out, but maybe next time around). Backlit keyboards, present in the original Air but absent from the late 2010 refresh, also make a return, while screen resolution, port layout, battery life, and general construction remain largely the same as the previous model.

What about the MacBook?

The refresh makes me wonder what Apple plans for its entry-level MacBook, which is making less and less sense within Apple’s lineup as the Airs become more competitive in speed and price. I'm not sure how the new Air has impacted MacBook sales, but since the Air is clearly the way forward for Apple's laptops and since Apple is more than willing to trim fat from its product line, anything could happen. If the 11" base model came with 4GB of RAM and a 128GB SSD, I would have no reservations about recommending it to people over the bulkier white MacBook, but unfortunately that didn't happen this time around.

The rumor mill is currently speculating, based on Apple's Q3 earnings call, that the white MacBook could be dropped from Apple's lineup entirely in favor of the 11" Air - we'll likely see the rest of Apple's Mac lineup refreshed before the end of the summer, so we’ll probably know soon enough. For my part, I think Apple would clean up if they could field an entry-level laptop in the $799 range, and they certainly could afford to based on their profit margins, but the company has never displayed any interest in such a thing. 

Update: Apple has removed the white MacBook from their online store so it appears that MacBook has been discontinued.


The Sandy Bridge upgrade makes the Air lineup a reasonable alternative to the white MacBook or 13" MacBook Pro, especially if weight is more important than processor speed This is particularly true of the in the 13" model, where the speed of the SSD and the higher screen resolution might actually make it better suited for some production work. The Thunderbolt port can also (either through dongles or dedicated Thunderbolt devices) make up for the Air's lack of FireWire and other high-speed connectivity.

If you were on the fence about the Air before, this healthy speed bump should make the thin-and-light laptops that much more palatable. If the lack of optical drive, FireWire, Ethernet, or hard drive space still put you off, though, this upgrade isn't likely to change your mind.

    If you do review, could you please cover sd card slot, whether it supports sdxc cards and read/write benchmark? Reply

    The new MacBook Air will support TDM, but, it appears, only between two Thunderbolt-equipped Macs/displays. I need to use TDM on a new MacBook Air with my G5 desktop which only has Firewire.

    Does anyone know where to find an adaptor cable to convert one end of the Thunderbolt cable to a Firewire one?

    I really feel that Haswell will be the solution, but by the Fall of next year we may have Windows 8, which has the potential to make a big difference in the Mac/Windows debate. 22nm will also be standard on these things and SSD will (hopefully) be cheaper. If one can wait 'till Haswell, it will be the best, but I'm guessing that holiday season 2012 will see tablets really moved into an even smaller niche. There is something to be said for a physical keyboard in a form factor barely larger than a tablet.

    According to the Intel statements they want $599 ultrabooks with Haswell... I think I can make it that far with my 2008 laptop.

    I hear MacBook is educational only now. Reply

    On the story, it shows a table with all the processors listed as 2 cores/4 threads and turbo boost up to 2.6Ghz. Is this true? On the macbook air website, they dont show turbo boost or hyperthreading for the macbook air. Is this a typo on the apple website(seems unlikely) or does the new macbook air not support these processor features. Reply

    I noticed that as well, every other Sandy Bridge mac makes explicit mention of HT and Turbo Boost. I hope the Air has them, they would really make it appealing to me. Without them, meh. I liked the last gen ones but you could feel it hit the processor wall often. Reply

    So far, the new MBA looks pretty sweet, except for one little detail. What about the screen? Right now Lenovo has a 12.6in eIPS screen -- the MBA uses a TN panel. If apple decides to put a decent non TN screen on the MBA, it's basically worth whatever they're charging. I've sworn a blood oath to not buy another laptop with a terrible TN -- or even a decent TN panel. I didn't see any detail of the screen's panel type, but Apple can secure my money right this second if they put a better class of display in the MBA, or anything else for that matter. Reply

    Even though it is a TN display it's still one of the better TN displays out there. The Sony Z, Samsung 9, and MBA all have very good TN displays. Sure its a TN display but we're not talking about the same TN screen you find on $500 laptops. And even though the Lenovo has an IPS panel, they're still using a craptacular 1366x768 resolution. I'm not sure what the point is to have a top notch IPS panel when you're going to handcuff it to that resolution. I'll take the higher rez Sony Z and MBA TN panels over a low resolution IPS panel any day of the week Reply

    For a company that has some pretty good displays on their mainstream consumer electronics and higher end Cinema display + iMac, its not too much to ask. 1366x768 isn't terrible on a twelve inch screen anyway. Dell used to have some pretty good 1920x1200 ultrasharp displays -- from a few years ago in a 15". It may have been a TN with pretty good viewing angles, but 1920x1200 is a lot of pixels in a 15" display. I think with the advent of great smaller displays on the iPad and better-than-TN eIPS panels, Apple could make a good product great. I'll take a slightly lower resolution IPS panel any day of the week. Reply

    It's not that TN screens suck, it's that TN notebook displays suck. All the quality gaming monitors for desktop PC's are TN. I have a 23" viewsonic that looks amazing from all viewing angles and it's a TN panel.

    Apple tends to put better TN displays in their products though. I'm not sure if these Air displays are of desktop quality, but you can be sure they are far better than your $500 windows notebook panels.
