Power Consumption & Thermals
I dug up my old power draw and thermal numbers from the 2011 MacBook Air review, retested the old models to ensure they still performed as expected, and added the 2012 models to the list.
First up is power consumption. Here we're measuring total system power consumption with the display running at max brightness and the battery fully charged. We are forced to use a different power adapter for the 2012 MacBook Airs so there may be some variance here but the power rating remains the same.
Cinebench shows a real reduction in power consumption under load. This is exactly what we expect to see from Ivy Bridge, which should translate into better battery life numbers.
The power savings are basically non-existant under HL2ep2, but you have to keep in mind that the HD 4000 is able to deliver over 70% better performance at roughly the same power level as the HD 3000.
Surface temperatures haven't changed all that much, at idle the 11-inch system measured a bit cooler than its predecessor while the 13 was within a degree.
Under load these things can get hot - despite the power savings it looks like the base of the chassis gets roughly as warm as it did last year. There's only so much you can do with a tiny chassis and a single fan. Note that during my Diablo III benchmarking pass I measured 45C just north of the F2 key on the keyboard on the 13-inch MBA.

What software is heavily crippled on Macs? Other than CAM/CAD which is very specialized, needs specific harware & is only used by a tiny minority, I cannot think of any.Either be specific or admit that you're full of FUD.

I've seen a lot of discussion on the AT forums and elsewhere, trying to tangibly represent the changes in GPU performance over a number of generations of Mac laptops and desktops, but specifically what you really get out of Intel's new graphics versus the older Nvidia solutions.I'd love to see some kind of reporting on the relative performance of things like:
Intel 2000
Intel 3000
Intel 4000
Nvidia 9400m
Nvidia 320m
----
Nvidia 330m/gt/whatever it was
AMD 6630M
Basically to see how Intel's graphics stack up against the systems that many people are currently using and upon which they are contemplating an upgrade. Perhaps it will be best times for a Haswell comparison so you can throw in Intel 5000 or whatever they decide to call it. But I do think people would find it valuable when considering something like:
"I have this first gen Core i7 CPU MacBook Pro with a 330m/gt in it, if I don't want a retina MBP, my only graphics option without spending $1800 is Intel 4000, how does that stand up to what I'm using now" etc etc.
Anyway, great review as usual, if i weren't already an rMBP owner, I'd be gunning for a 13" MBA.

I agree, they should be added to Benchhttp://www.anandtech.com/bench/GPU12/372

I can attest to frequent GPU issues, display corruption, other nonsense with my AMD equipped (6970M) iMac.I'd much rather they keep diversity between manufacturers in their product lines (even if it is generation to generation), but the drivers are kinda crap.

If I remember correctly, IGZO will be able to reduce the amount of backlight that is caught in the panel. So a higher resolution panel would not necessarily mean increasing the backlight to get the same brightness. :-)TEAMSWITCHER - Monday, July 16, 2012 - link
When I was in college my computer traveled back and forth with me in multiple large boxes. These new MacBook Airs (and the PC Ultra-books) are dream machines for college bound young people, vastly more powerful than the machines I used back in the day. As a Computer Science major having such a device constantly at my fingertips would have been truly life changing! So...Use them for good, and not evil.wditters - Monday, July 16, 2012 - link
Hi Anand, are you sure about the Samsung color profile that your put up for download? It seems awfully off and washed out ... Cheers.billgerr - Monday, July 16, 2012 - link
May get high-end 11-inch MBA as replacement when E4300 bites the dust. I like the E4300, but to this day have not owned a successor to Digital Equipment Co. (can't use term DEC anymore, as few recognize brand) Hi-Note Ultra. IMHO one of the sweetest designs ever, even with its blazingly fast 486DX CPU and floppy-disc wedge.Osamede - Monday, July 16, 2012 - link
This article claims:"....Ultraportables prior to the MacBook Air's arrival in 2008 typically sacrificed in one or more of the above areas......"
Wrong, wrong, wrong. There was the Panasonic Y series Toughbook, as well as the Soy SZ and Z. All of which far outperformed the MacBook Air. I had the Y5 with 14" screen 1400x1050 resolution, 8 hours useful life and it was 3.5 lbs WITH a DVD drive. The Sony Z11 and 12 for example pack power that even the most recent Macbook Air released NOW in 2012 still cannot match - and they also had 13" 1920x1080 screen and a "low end" model with 13" 1600x900 screen.
The way Apple fans are trying to re-write history is scary.

What part of "typically" you understand? That doesn't mean that there weren't ANY notebooks, just that they weren't typical of the class.Here is the full context:
Despite the recent Ultrabook frenzy, the MacBook Air was one of the first (if not the first) to marry performance with usability, screen size/resolution, portability and battery life. Ultraportables prior to the MacBook Air's arrival in 2008 typically sacrificed in one or more of the above areas.
The Panasonic Toughbook was 1.9" thick. That fails the portability test:

The Vaio Z series fits the bill, but is significantly more expensive than the MacBook Air. Ultraportables have been around for years, but mostly they had small screens, were thick, had bad keyboards. Heck, even Apple had the Powerbook Duo in the early 1990s.
The Air in 2010 was the first successful attempt to make the ultraportable mainstream. In 2008, it did offer a full size screen and keyboard, and was extremely thin, though it was still pricey.
The way some anti-Apple people are trying to re-write history is scary.
