The MacBook Air: Thoroughly Reviewed

During Jobs’ keynote, Apple mentioned that the Core 2 Duo in the MacBook Air was 60% smaller than standard Core 2 Duo processors. A quick look at Intel’s mobile Core 2 Duo datasheets reveals that indeed both the micro-FCPGA and micro-FCBGA packaged Meroms measure 35mm x 35mm. Is it possible that Intel designed a completely new package just for Apple?



It turns out that the answer is a surprising: sort-of. At last year’s Fall IDF Intel talked about Montevina, the successor to Santa Rosa due out in the second half of 2008. Montevina would combine a new chipset (Cantiga) with mobile Penryn. In addition to Montevina Intel will also release Montevina SFF, a smaller package version of the platform that reduces overall chip footprint by around 60%.



Pay attention to the size of the CPU, it drops from 35mm x 35mm down to 22mm x 22mm - Penryn SFF is around 40% of the size of regular mobile Penryn, which happens to be the same size as Merom.

It looks like Intel created Merom SFF specifically for the MacBook Air, a product that wasn’t in Intel’s lineup or roadmap but one that Apple needed. Remember that the first chip that will look like this wasn’t scheduled to be out for another six months with Montevina SFF.

It’s not clear whether Intel will make this custom Merom available to other OEMs (we’d suspect they would if there was enough demand), but it’s a tremendous feat on Apple’s part. This isn’t the first time Intel has put together a one-off chip for Apple; if you’ll remember, the CPU in the Apple TV was a special Dothan that wasn’t a part of Intel’s standard lineup.

We’ll have a look at the MacBook Air as soon as they start shipping, if you’re ordering one now we’d recommend taking the SSD option if you can afford it. At $999 it’s pricey, but it should help keep heat down in the chassis and performance should be better than the pitiful 1.8” HDD in the system, which we suspect will end up being its weak point.

We also can’t help but think that a Penryn based MacBook Air would be far more desirable thanks to lower thermal output of Intel’s 45nm chips. If you are fine waiting, a MacBook Air in the second half of 2008 will give you slightly better performance, better battery life and should keep your lap a lot cooler.

Our MacBook Air just arrived and before even turning it on we had a few burning questions we had to answer. These questions of course required us to break out the screw driver and open up the poor little thing.

The MacBook Air is surprisingly easy to take apart, you simply have to remove 10 screws from the bottom of the notebook and just pull the base away. There's no prying, no heat gun and no special tools required. This was infinitely easier than taking apart the iPhone.

With the bottom off you'll see this:

The big black thing that takes up the majority of the real estate is the Air's battery, to remove it you simply unscrew it from the chassis:

With the battery out of the way the MacBook Air is much simpler on the inside. The upper left houses the hard drive and next to it is the motherboard. The little thing in the lower right is the wireless adapter.

We wanted to accomplish two things: get a closer look at the hard drive and have a look at the SFF CPU/chipset that we'd been so obsessed with a couple of weeks ago. Getting the battery out wasn't a problem, but replacing the hard drive proved to be a little more challenging.


A Second Shot: Windows Vista SP1

It’s hard to say the last year has been anything but rough for Microsoft’s Windows division. Although we found Windows Vista favorable upon its launch last year after watching it go through an usually drawn-out development process, such a sentiment hasn’t been shared by Windows users as a whole. Windows XP proved to be every bit the competition for Vista that Microsoft could ever fear it would be, at the time as when Vista was having its own post-launch pains. It was a bad combination, making for a bad year for Microsoft’s efforts in pushing its first new desktop OS in 5 years. Microsoft was looking to make a solid case for why Vista is a worthwhile successor to XP in a market notorious for a resistance to change, and they failed to do this thanks to a failure in immature technology and an inability to get a consistent and convincing message out.

In the year since then you could make the argument that Microsoft’s marketing efforts still haven’t improved, but you would be hard pressed to make the same argument about Vista itself. Since its release an unfortunately large number of bugs and quirks have been discovered in Vista, which has kept Microsoft busy patching them over the year, while to their chagrin many consumers sit on the side watching. To Microsoft’s credit they’ve done a lot with Vista well before the first service pack, various patches including the reliability & compatibility packs released over the last year have solved many of the earliest complaints about Vista; it already performs better and is less quirky across the board now than when it launched. But it goes without saying that this hasn’t been enough to solve all of Vista’s problems, putting a lot of watchful eyes on Service Pack 1.

There is a saying among software development circles that businesses as a whole won’t touch a Microsoft product until the first service pack; they would prefer to wait until a product has been widely used and the biggest problems identified & solved. It’s cold but effective logic that also puts a great deal of pressure on Microsoft. No matter how good (or bad) a product is, half of their customers won’t bat an eye until there’s a service pack, making the first such pack just as important as the product launch itself in some ways. Complicating matters further with the Vista launch in particular is that Microsoft has tied Windows Server 2008 to the Vista kernel; getting Windows Server 2008 out the door means any and all Vista problems that would hinder server operation need to be eliminated. The result is that Service Pack 1 is a big deal for Microsoft, they need to show consumers that they can fix what still ails the OS, they need to show businesses that it’s now ready for them to use, and they need to show server administrators that the core technology is so good that a reliable server can be built off of it.

Furthermore, with the progression of technology in the last year the timing couldn’t be any more critical. The 4GB address space barrier for 32bit x86 is finally beginning to rear its head with more average computer uses; RAM prices have nosedived with 8GB of RAM going for as little as $160, resulting in a wide and very real need for a 64-bit operating system (and XP64 being a poor fit for consumers). Meanwhile PC OEMs are finally warming up to the Extensible Firmware Interface (EFI) and are ready to start building systems with it, meaning they too must move beyond XP. Even governments are finding they need to move to Vista as of late, as new encryption standards come in to play which only Vista supports.

The result of this is that many different groups have been watching SP1 far more intently than past service packs. With the final version of SP1 in hand, today we’ll be looking at what Microsoft is bringing to the table with Vista’s first service pack. With a combination of new features, bug fixes, and performance improvements, there’s a great deal to this service pack that we’ll be covering so let’s get started.
