The Battery Life
Light Web Browsing
Here we're simply listing to MP3s in iTunes on repeat while browsing through a series of webpages with no flash on them. Each page forwards on to the next in the series after 20 seconds.
The display is kept at 50% brightness, all screen savers are disabled, but the hard drive is allowed to go to sleep if there's no disk activity. The wireless connection is enabled and connected to a local access point less than 20 feet away. This test represents the longest battery life you can achieve on the platform while doing minimal work. The results here are comparable to what you'd see typing a document in TextEdit or reading documents.
As glorified typewriters, you can’t beat the battery life offered by the MacBook Air. Light web browsing, document creation and music playback have minimal impact on the Air’s battery life. In fact, we actually beat Apple’s battery life claims in our light tests. The 11-inch Air delivers nearly 7 hours on a single charge and the 13-inch managed 11.2 hours. For a writer, you can’t do better than this.
Flash Web Browsing
The test here has three Safari windows open, each browsing a set of web pages with between 1 - 4 animated flash ads per page, at the same time. Each page forwards onto the next after about 20 seconds.
As always, the display is set to 50% brightness, audio at two bars, screensaver disabled and the hard drive is allowed to go to sleep if idle. The wireless connection is enabled and connected to a local access point less than 20 feet away.
If you use the MacBook Air as a full function P...err Mac, the battery life drops steadily. In our Flash web browsing test battery life dropped to 4 - 5 hours depending on which Air you’re looking at. And the difference between the two isn’t all that great. The 13-inch only managed an extra 30 minutes of battery life.
Multitasking Battery Life
Our final battery life test is the worst case scenario. In this test we have three open Safari windows, each browsing a set of web pages with between 1 - 4 flash ads per page, at the same time. We're also playing an XviD video in a window all while downloading files from a server at 500KB/s.
Our heavy multitasking test is the biggest issue. Neither MacBook Air was able to deliver more than 3 hours of battery life on a single charge. The problem here isn’t just battery capacity but also the performance of the CPUs themselves. A major component of long lasting mobile battery life is a concept known as rush to idle.
Let’s say we have two CPUs. The first is an ultra low power CPU that only consumes 10W under load, but 0.5W at idle. The second is a high performance CPU that consumes 40W under load and 1W at idle. If it takes the first CPU 5ms to decode a frame of video at 10W but the second CPU can do it in 1ms, the total energy consumed over 33ms is is 0.064J for the first CPU and only 0.036J for the second CPU.
The longer the first CPU is idle, the more its typical and idle power advantages will come into play (hence the results in the light web browsing test). The more CPU bound the workload however, the more the advantage over the second more high performance CPU will disappear. Our heavy downloading/multitasking test is the most CPU bound of all of our battery life tests and the workload is consistent regardless of how fast you execute it. In other words, a faster CPU won’t be able to do more work, it’ll just be able to rush to idle quicker.
The battery life story boils down to your usage model, even more so than with the MacBook Pro. Light users are going to get wonderful battery life out of the new MacBook Air, particularly the 13-inch model. However, if you are the type of user who does a lot of multitasking or if you’re running particularly CPU intensive apps (e.g. Photoshop, iMovie, etc...) then these two notebooks will hardly last you. I suspect this is the distinction Apple is looking to make. If you’re a regular user, just playing around on Gmail and browsing the web then the MacBook Air is all you’ll need. If you are doing any work with your machine however, you’ll want to look towards the MacBook Pro.

Instead of "jives with" should be "jibes with" ...Exelius - Wednesday, October 27, 2010 - link
I'm a huge Apple fan - but I'm just not drinking the kool-aid on this one.I have a 15" MBP and it's really not that bad to carry around. It also gets like 5-8 hours of battery life (3-4 with VMWare running) and it runs Windows 7 under VMware very well with 8 GB of RAM. I've never considered portability an issue and while it's an expensive machine, I don't think you'd own an MBA. I doubt the MBA would have nearly that type of battery life under VMWare.
The iPad seems like a better form factor for the "couch computer" (i.e. looking up shit on IMDB or googling something to settle an argument while watching football.)
IMO the MBA seems like a poor man's MBP. i.e. for students looking for a cheaper computer; the "super-thin" part seems almost like a gimmick to convince people it's a premium product. Really, the only drawback of the 15" MBP (even the lowest-specced one) is the price.

The thing's hardly faster than my Ion netbook. There will be lots of thin designs coming out like what Intel showed at Computex. Core 2's two generations behind.For now, I think the Acer TimeLineX 3820TG is still the best ultraportable laptop (certainly the fastest anyway).

As for an alternative for sub 5 lbs powerful laptops and as for the M11x being fast: I am typing this line on a Acer TimelineX 3820TG with 450M and switchable HD5650, which is on a totally different level than either the MBA or the Dell (while being half the price).- 3.9 lbs
- it can do 9000-10000 points in 3dmark06 easily with a little bit of raised clocks (one click in AMD GPU tool). In games it's even faster, as the ATI cards are much better in real games than in benchmarks.
- if you are lucky, you can overclock CPU to 3.3 Ghz (or swap to a 580M and OC-it to 3.8 Ghz, with sub-75C temperatures!)
- and easily do 6-8 hours while web surfing
- has dual fan / dual heatpipe cooling
Other than that, it has the most horrible keyboard I have ever seen, with a cheap AUO screen, noisy mic and poor warranty service and a gazillion of running applications, including two real-time virus scanners on the factory install. But a review would be really interesting to see! I seriously think the 3820TG with HD5650 is without alternative in the powerful but portable notebooks, if possible, please make a review about it! (in North America, I think it's only available with 370M processor, while in Asia they sell it with anything up to 640M).

Intresting system, but i wouldent use it. the keyboard looks to have flex under light loads, making me think that although it looks great on the outside the inside might of had to make some structual sacrifices for the bigger specs, not to mention that the lack of a backlit keyboard would make it more inconveniant compared to what i have now.But it does like they are trying to improve there build quality, its just not to the point that i would like.
As nice as the specs are, i just cant bring myself to trust there build quality just yet, however it does look like there at least trying to improve so who knows perhaps there will be an acer on my list of potentials the next time im do for a notebook upgrade.
as for comparison to the air... i think there oppisets in some respects. the air's performance although weak at best can still fit in nearly any bag making it conveniant to find a place to stow it for those who have bags full of books and junk, where as the acer trys to push for a more heavy multimedia experiance with a good compact form facter and a extended battery.

1/ SD card reader2/ mic on front for skype/VoIP
The 11" netbook would be a absolute winner (and an order of magnitude upgrade for people using Atom netbooks) . But why did they miss the SD card reader? This is so obvious, and a determining feature what makes one brand/model of netbook a winner over another brand/model. Such a simple and cheap port. Even the iPad has an SD card reader!
And what on earth are they doing putting the mic on the side like that? While it *might* be OK when sitting indoors at a tidy desk without other ambient noise, it certainly is not clever in most "real world" situations.
I would love to replace my ever-so-slightly too noisy and underpowered (but magnificent screen and full of ports) SONY W11 netbook. But no, not until Apple fix the mic location and provide an SD slot.
(I use SD slot for camera - saving local or uploading to fileserver/website, for camcorder - and immediate playback of material recorded, for old-fashioned mailing of data/documents, for a TASCAM HQ digital audio recorder, and for file transfer with colleagues and for file backup when out of the office, I need highest possible robust mic for indoor and outdoor skype/VoIP where my office telephone is forwarded to my laptop through SIP )
These two points may seem like tiny features, but I think for many people they are showstoppers.

I'm not sure why everyone thinks an SD card slot is a "must have". For one thing, there are still quite a few cameras that *don't* use SD cards (like virtually any high-end DSLR) and putting a technology in your laptop that might not even be viable in 3-5 years is not exactly a good idea. Buy a 9-in-1 card reader. They are like $20. They are about the size of a deck of cards and can handle almost any type of flash.I would MUCH rather have a 3.0 USB than a SD card slot -- infinitely more useful.
kmmatney - Wednesday, October 27, 2010 - link
SD slots are useful for permanent storage. I have an 80GB SSD in my Dell Inspiron 9400 laptop, but needed a little more storage. So I just keep a 32 GB card in the SD slot, and it gave me enough room for everything I need. I use it mainly for documents, presentations, and backups of important work from teh SSD. It only sticks out about 2 mm, so I can keep it on all the time. I've even run VMware images from it, and it wasn't too bad.I agree that a USB 3.0 slot is useful as well, but wouldn't want to lose the SD slot - its like having a second, easily removable, hard drive.

I see it as a replacemenct for the optical drive, since its also used in cameras, video recorders, and ebook readers (i have an SLR that uses these and a ebook) it makes them alot more conveniant since most notebooks come with the slot already. it puts the macbook at a disadvantage becaus now people have to carry around a card reader that would not be neaded on other notebooks.It would be such an inconveniance if i had to drag around a reader with me, and since alot of apple users do photo and video editing it looks like a bad oversight not being able to transfer images and videos without extra required hardware.

So I am posting late here. I read this last night, but was too tired to respond.So now a lot has already been said. But here is one thing that keeps boggling me.
WHY do people keep calling this a Netbook when it clearly *IS NOT*. The 11.6" MBA is an ultraportable. In line with other ultraportables out there. Its not a cheap piece of plastic with a laughable screen, keyboard, graphics, or atom processor. The benchmarks clearly show this machine to run circles around an atom.
And if you compare it to similar machines of weight, size, and speed its not far off the mark from a price concern either.
Is it a perfect machine, no... But it looks like it will fill the gap that has been missing from the Apple product line since the demise of the 12" PowerBook.
