The MacBook Air: Thoroughly Reviewed

Battery Life
When Apple announced that the MacBook Air would have a 5 hour battery life I couldn't help but laugh. As Charlie over at the Inquirer pointed out, Apple did nothing new with the MacBook Air. The tough engineering was done by Intel and the component suppliers, Apple simply designed the chassis. Because Apple is doomed to use off the shelf components like everyone else, there's no magical way Apple can deliver 5 hours of battery life where its competitors have failed.
Close to 5 hours is attainable on the Air, but only in a very light usage scenario. Realistically you're looking at 2 - 4 hours of battery life out of the MacBook Air depending on what you're doing. In order to help set expectations, we've got a few battery life tests we put together (the descriptions of the tests were mentioned earlier on the SSD battery life page).
Apple's 5 hour claim is laughable but not as much as I expected. If I wanted to I suspect I could hit 5 hours by making the web browsing test less stressful, but my focus was on real world usage scenarios, not proving Apple correct. Regardless, 4 hours and 16 minutes doing what I consider to be the intended usage model of the Air is respectable. It's not great, but it's not terrible either.
The SSD improves things considerably, and it's worth noting that the fastest MacBook Pro can also offer similar battery life despite having a more power hungry CPU and screen (thanks to a larger 60WHr battery). The aging Core Duo based MacBook Pro put up an absolutely dismal time, which just goes to show you how much things can change in two years.
The DVD playback test is also decent, you can watch a full length movie on the Air (even The Godfather). But watching two back-to-back isn't possible (although I do think you could squeeze two viewings of Rambo in there and frighten your fellow airline passengers).
Once again we see that the Air gives us better battery life than the original MacBook Pro, and a time that's competitive with the fastest MacBook Pro. Armed with an SSD, the battery life is the best Apple offers today.
And then we have the multitasking scenario. At just under two and a half hours, this isn't your do-everything notebook. That should've been obvious from the get-go with the whole lack of an optical drive, 2GB memory limit and no built-in Ethernet port. The MacBook Pro advantage here is the greatest it has been in all of our tests, giving almost 30% more battery life than the standard Air.

You are correct - it looks like the power draw is identical to any other USB optical drive. I don't see any indication of any hardware based authentication tied to the drive, although I haven't specifically tested it.Take care,
Anand

Wow. Thank you very much for looking into it. IF you do get a chance to test out the drive on another MBA, I'd sure like to know the result. I'm really hoping they haven't invoked any limitations similar to Remote Disk under the assertion that people could use it to share media content.Cheers,
Brau

Bravo Anand. I loved the review, and it reminded me of why I started reading Anandtech in the first place.I honestly couldn't care less about the Macbook Air, but the review was top notch.

So Anand...Seriously.. the Mac koolaid is making you drunk.
Youd be "blown away" if Dell and Gateway took away the removable batteries from their existing thin and lights (they dont make ultraportables, and neither does Apple), made them thinner, and removed a bunch of ports and the optical drives?
Were you "blown away" by the Sony X505? Or how about any of the MANY PC based notebooks that are a LOT smaller and lighter than the MBA?
I guess not. They're not that nice white color with the Apple logo and arent held up by Jobs at the Mac expo.
Are PC guys really getting THIS desperately bored that now we're going to join the flocks swooning over any crap Apple chucks into the marketplace?
At least be honest man. If the MBA had a Dell or Gateway logo you would TEAR IT APART for lack of ports, too large of a footprint, weight that was mediocre since there is a BIG list of sub 3lb PC notebooks and.... NON REMOVABLE BATTERY.

Not to be picky but, well, *PC* reviews are always picky. There is NO WAY the MBA is an "ultraportable"Its HUGE in terms of the dimensions that mean something - LxW. It is a THIN AND LIGHT.
Im typing this on a Fujitsu P1610. THAT is an ultra-portable - 9.1x6.5x2.2lbs
13x9 is massive. My Sony SZ had similar dimensions and I couldnt open it in a cramped coach seat on a plane.
People keep talking about how "the MBA is for special people - you dont get it". MANY of us *do* "get it". There are ALOT of travelers like myself who have been using notebooks in this space for YEARS.
Apple has given us yet another ~13x~9x~3lb notebook. The only difference is this one is THINK (useless) and has NO REMOVABLE BATTERY (big problem)
I keep seeing Mac lunatics ranting about how the battery *IS* removable because you can surgically remove it. Its funny because thats pretty directly counter to the argument of "only special people use this type of notebook" since those "special people" are executives and road warriors who NEED TO SWAP BATTERIES WHILE ON A PLANE and also need to open the thing on a plane.
Sorry to all the drooling Mac-o-philes, but the MBA is a miss.

But but... its only 10 tiny screws of varying sizes that need to be removed to change the battery - anyone can do that on a plane!;)

13.3" screen and 3lbs...Why not a
faster laptop
heckuv a lot more durable (proven)
2.2lb (26% lighter!)
upto 4GB of ram
upto 200GB SATA HD, not old school PATA...
Wi-fi a/b/g/n + EVDO broadband (Verizon or AT&T...you can choose!)
you can CHOOSE what CPU, RAM, an HD you want....
fingerprint reader
hardware based security encryption (if you set it up and lose your laptop the data is %100 safe)
choice of 4 or 8 cell battery....carry an extra and change without taking 10 screws out...or upgrade at any time
can be purchasd in tablet-form...uber cool
Oh yeah...prices start at hundreds less than Macair
what am I talking about?? Lenovo X61...and other laptop makers are in the SUB 3lb market....
True...Lenovo's development is way more experienced at ultra-portables than Apple... and I do say the Apple is "pretty" and sleek... but if I had a kid in college, I'd spend the $$ on a Lenovo laptop as I know it'll take the abuse much better than the Macbook air and heckuv lot less likely to be stolen...
My $.02...

And a X61 with a Penryn, 100GB HD and Ultrabase+DVD is $1600 vs. Air+DVD $1900.Only comparison negatives: with an 8 cell X61 is 3.3 lbs and resolution is XGA, not WXGA+.
(And the 4 cell weighs 2.7 lbs. not 2.2 lbs.)

What happened to the special, customized, and powerful Core 2 Duo CPU that Intel designed just for Apple?
aliasfox - Thursday, February 14, 2008 - link
It may be 50% faster than the 1.2 GHz ULV processors in most other ultraportables, but that also means it's also about 50% slower than most mainstream high end CPUs (2.2 GHz and up).Slow hard drive doesn't help either.
