The MacBook Air: Thoroughly Reviewed

Inside the Air
The MacBook Air uses a 65nm Merom based mobile Core 2 Duo CPU running at 1.6GHz. For an extra $300 you can upgrade the chip to a 1.8GHz part (note that Intel only charges Apple an extra $32 for the faster CPU). Despite the high markup we do recommend the faster CPU since its soldered onto the motherboard and you can’t upgrade it yourself after the fact.
The CPU used in the MacBook Air isn’t your run of the mill mobile Core 2, instead it uses a new small form factor packaging that Intel was originally going to debut at the end of this year. It seems as though Apple (and maybe other partners) put enough pressure on Intel to introduce the SFF chip/chipset packaging earlier than expected, enabling designs like the Air.
The CPU and chipset die aren’t any smaller, but the package that the die sits on is reduced by approximately 60%, enabling a smaller motherboard footprint.
The CPU runs at a lower voltage than stock mobile Core 2 processors, but at a higher voltage than the LV (Low Voltage) Core 2s. We hypothesized that the reason for a higher voltage than a LV chip was because of the more exotic packaging, requiring a higher core voltage to ensure proper power delivery to the chip.
The motherboard is quite compact, looking more like a board from a large smartphone rather than something you'd find in a Laptop. Most of that is because there is no expansion on the board, everything is soldered on.
Integrated Graphics
In order to limit motherboard footprint and power consumption, Apple stuck with Intel's GMA X3100 integrated graphics on the Air. The GMA X3100 is by no means a bad solution, especially if driver support is good (Apple does much of the driver development for OS X so it's difficult to compare) but it's far from fast. Luckily this is one of those situations where OS X not being a gaming platform works in Apple's favor.
The X3100 is fast enough for most OS-level operations, although functions like Exposé are choppier than on discrete graphics thanks to the lack of any local video memory (video memory is carved out of system memory).
Coverflow's animations work as smoothly as they do on the Mac desktops, it's mainly the memory intensive video operations that can get sluggish on the X3100. That being said, you need to have around 25 windows open before full screen Exposé really gets distractingly choppy.
Professional applications that have discrete graphics requirements obviously won't work on the GMA X3100, but we don't expect the Air to really be used as a professional workstation.
Video out on the MacBook Air is limited to 1920 x 1200 since it's only got a single-link DVI output. Enabling an external display is really simple - just plug it in and everything works.

actually a lot less "cool" but a much better option would be a panasonic T5 thicker but lighter than the MBA but with twice the battery life... and that last is really important in something you always carry and use all day, anything which can't go a full day without a charge is just not worth the expense (I know the T5 will do a UK->West Coast flight on a single charge).The only real loss is less performance (do you really need it on the road??) and nowhere near as nice a screen.
Really depends on what your usage is... but I'll get a T5 when my current notebook goes thanks.

"OK, so then the Sony TX, the Fujitsu P7k, the Toshiba Portege, the Dialogue Flybook, the Panasonic Toughbook, the Dell XPS1210, the Sony SZ, The LG XNote."The only one in this list that could compare with the MBA is the Portege, and even here it feels and looks like a plastic toy in comparison to the MBA. The display isn't near as sharp or bright on the Portege, and it's much slower. I owned the Sony, and Anand's review is right on: the cramped keyboard and tiny display made it a definite chore to use ergonomically.
So, yes, just like the MP3 player (iPod) and smartphone (iPhone) Apple has taken the ultralight class, studied what others have done, and have set a new benchmark by redefining what is possible with these devices.

"Redefining what is possible with these devices?" That's taking it a bit far, and I'm a rabid Apple fanatic. The MBA is a first effort, and just that. I spent a good amount of time playing with one at the Apple Store yesterday, and the only thing I can say about it is that it is simply too large. I can do without the ports, the external drive, the non-removable battery, etc., since none of those things really affect how I use my laptop. But if the MBA were reduced to an 11" or even 12" screen with a slightly smaller bezel around the screen, I would buy one. Until then, it's worth it to just carry the extra two pounds and buy a MacBook.ninjit - Wednesday, February 13, 2008 - link
Regarding the 8 hour time-to-charge you noticed a few times. Did you calibrate the battery when you first got the Macbook Air.I've seen similar behavior on Macbook Pros before, when new or after buying a new battery - and it's almost always because the user failed to collaborate the battery initially.
It's one of those simple things that manufacturers tell people to do (for good reason in this case), but most ignore.

I noticed that you missed the page down and page up buttons. I have to say that I like scrolling with the trackpad much better. Place two fingers on it and slide downward makes this a nice feature.To me the LED backlighting made the blacks a little richer and less prone to showing bleed like the regular LCD on the MacBook, did you feel this way too? I wished that LED backlighting is available for the regular MacBook like the one I just bought.
I like the way Apple did keyboard lighting on the Air than the one on the MacBook Pro. Black keys with lighting works much better than lighting on silver keys in my opinion. This being said I get by just fine using the light from the screen to illuminate my keys.
On a final note, there's no need to miss the right click button on the track pad, I just set the pad to accept clicks and allowed for two finger tapping to be a right click. I find it pretty difficult to go back to other laptops.

When I first heard rumors of the Air I was excited. But seeing that there is no opportunity to upgrade it is worthless to me. For $1800 the ability to upgrade should be standard. This makes me really enjoy the smaller and more affordable EEEpc. If the purpose is just basic internet and note taking the EEE is a much better choice for a college kid, then the overpriced Air. I see the air as a status notebook, at 13.3 it is not really an ultra portable, yes it is light but the form factor is not that portable. I believe the size of the EEE is about as small as one can go without serious drawbacks. I think the Air will sell like the iTV. I just wonder why Apple would release this subpar product following the iPhone? You would think it would have been a tablet and actually had a smaller form factor. As of now the Air is worthless compared to other portables. Why would anyone buy this when the Macbook has better specs and is only 2 pounds more. The thinness of the Air is a gimmick and really doesn't provide much more portability.Griswold - Tuesday, February 19, 2008 - link
But its a clear winner! This is why:http://www.abload.de/image.php?img=macbookcommodor...">http://www.abload.de/image.php?img=macbookcommodor...

""EEEpc. If the purpose is just basic internet and note taking the EEE is a much better choice for a college kid""I dunno, the EEEpc is way too small. In my job on the road, field and office I need a light machine that has REAL keys. My fingers are large since I do actually do 'work' in addition my eyesight isn't what it once was. The tiny screen on the EEEpc might as well be an iPhone with the text size. And for heavens sake, if the 'Surf' EEEpc has a RAM slot, darn-it, put a door on it so you don't have the pull the machine apart! I also, much as I dislike it, must have perfect Word, Excel and Powerpoint compatibility, (Watching a colleague running Ubuntu on a Thinkpad July of last year for a pre-made company presentation was painful) the OEM linux 'office like' application doesn't give me that, at least there is office on the Mac. And don't say run XP on one of those, I deal with enough XP foibles as it is then to have to run it on a 7" screen with cramped keys. As it is the Air probably barely fits for me, but the EEEpc just goes way too far size wise and is even less of use.

I can't wait for Anandtech to review the Lenovo X300 and do a side-by-side comparison:http://www.maccomplainer.com/macbook-complaints/le...">http://www.maccomplainer.com/macbook-complaints/le...
I still think the main disadvantage of the MB is the 4200 RPM PATA. If I were a business user, the HD speed would drive me insane with all the documents and spreadsheets I may have to edit on the plane, train, etc.
