Final Words
Whereas last year's MacBook Air was a good machine for light work, the 2011 models are true replacements for mainstream portable Macs. There's still no dethroning the MacBook Pro (although the 13-inch model clearly needs a higher resolution display option), but for the rest of the world there are now some excellent ultra portable options that don't force you to really compromise on performance.
Both the 11 and 13-inch MacBook Air are fast enough to replace your 3 year old MacBook Pro and still deliver better performance. You can even move from a 2010 MacBook Pro to an upgraded MacBook Air and not notice any drop in performance. All of this is thanks to Intel's Sandy Bridge CPU.
From left to right: 15-inch MacBook Pro, 13-inch MacBook Air, 11-inch MacBook Air
It's the GPU performance that I'm less excited about. While last year's GeForce 320M isn't significantly faster than the HD 3000 in the new MacBook Air, it's still faster in our tests. There's not much Apple could've done about this. I don't believe a discrete GPU in an Air makes sense, but this should be a clear message to Intel. Sandy Bridge's GPU is the bare minimum, we need to really see a real ramp in performance from here on out. Ivy Bridge will give us a bit of that but not another doubling in GPU performance. Perhaps we'll see something significant from Haswell in 2013. For now, if you like gaming on the go you'll have to get a MacBook Pro.
When it comes to battery life the new MacBook Air doesn't break any records, but it doesn't disappoint either (at least under OS X). With the exception of the our light web browsing test, the new MacBook Air behaves pretty similarly to last year's model on battery power. The new 13 doesn't do anywhere near as well in mostly idle scenarios but under moderate to heavy load the new MBAs last at least as long as their predecessors.
The only move I would be careful about is a downgrade from a 13-inch 2011 MacBook Pro. The new 13-inch MBP is still considerably faster than the MacBook Air, while the more portable form factor is tempting you're better off waiting to see what Apple does with the next update to the MacBook Pro.
If you were a fan of the original MacBook Air, the 2011 models are just as significant of an introduction as the very first one in 2008. They may not look any different from the outside, but the new 11 and 13-inch MacBook Air are a significant step forward. These systems are no longer niche ultraportables, they've instead brought the ultraportable niche into the mainstream.
If you're stuck deciding between the two I think it breaks down like this. If you've got a beefy system at home and just need something portable for travel, the 11-inch Air is perfect. It's now fast enough to get real work done on the road and portable enough to feel like a tablet with an integrated keyboard. If you're replacing a primary notebook however, the 13 is the safer bet. It is sized like a normal notebook, you get longer battery life and a bigger screen to look at. If you're a fan of extremes, the 11 is for you. If you like balanced compromises, go with the 13.
What happens from here on out is what's really interesting. Intel has already committed to moving the TDP of its mainstream parts from 35W - 45W down to 10 - 20W. Since the Air is the new mainstream Mac notebook, Apple has already made that move. The performance in this 10 - 20W segment is going to get much better over the next two years, particularly once Haswell arrives.
The Thunderbolt Display is the first sign of what's to come. Moving IO controllers and expansion into the display, and potentially even moving discrete GPUs out of the notebook are all in store for us. Apple is really ahead of the curve here, but it's easy to imagine a future where laptops become a lot more like the new Air and shift to a couple high bandwidth ports instead of numerous lower bandwidth connections.
There's a lot to like with the new MacBook Airs; the last update was good, but performance was still often lacking. The MBA 11 in particular is now much more useful, and the 13 rightfully spells the end of the line for the old MacBook. While pricing is higher than typical 11" to 13" Windows laptops, you really can't find a competing Windows laptop with all the features the MBA offers without paying a similar price premium. You get a nice chassis with excellent build quality, decent displays that trump every budget laptop we've looked at, and reasonable battery life. If you like thin and light ultraportables, the MacBook Air continues to be one of the best options around.

I'd like to know too, in fact I think a decibel reading for laptop reviews would be great.solatic - Thursday, July 28, 2011 - link
"... [It's] easy to imagine a future where laptops become a lot more like the new Air and shift to a couple high bandwidth ports instead of numerous lower bandwidth connections."I agree in a sense, but I very much disagree with the manner of your idea.
Getting rid of low-bandwidth ports on laptops is stupid because these low-bandwidth ports are industry standards. The standard display jack for projectors everywhere, from business rooms to classrooms etc., is VGA. Good old VGA from the 90's which was never displaced by HDMI or DVI despite their ubiquity and technological superiority. Why is irrelevant, but my point is that I can't tell you how many people I've seen with Apple laptops who time and again have asked to borrow my machine with its VGA port because they can't find their VGA dongle or forgot it at home/the office.
VGA, RJ-45, USB - we don't use these jacks because of how much bandwidth they move but because we know we will encounter devices in the field that will use them.
What you really want, Anand, is a docking station. Lenovo/IBM has/did made/make them for some time for the Thinkpad line. You come to the office, slide your laptop in, and boom - the docking connector is a high bandwidth connector that connects you to network, display, audio, interface, etc.
The only real problem with docking stations is that they're either proprietary (the Thinkpad ones) or they're too slow for higher-bandwidth applications (USB docking stations). If you see a future in Thunderbolt docking station-type devices - like the Thunderbolt display - then this is a good thing. The Thunderbolt display can now be used by any Apple computer with a Thunderbolt port - whereas Lenovo has to manufacture different docking stations for the X and T series and these docking stations can't be used with Toshibas, Apples, Dells, etc.
But to propose getting rid of VGA and RJ-45 ports now is not something I can agree with. Put Thunderbolt on new machines, make Thunderbolt projectors etc., wait for them to saturate the market - and then, only then, does it really make sense to get rid of these slower ports.

It certainly makes sense to ditch VGA on a product like the MacBook Air, since a VGA port is too large to physically fit inside it. And it makes sense on all other laptops since most people would rather have 10 more mins of battery life all the time than a VGA port on the odd occasion that they need one. I propose that those who own archaic video devices lacking a digital interface buy a $5 adapter and leave it attached to the device, that way people with modern notebooks can connect to them without issue.The lack of a wired Ethernet port on the Airs is also due to its ultra slim profile, but it amazes me how many people I know that have no idea that they can plug their laptops into a wired network and get far better throughput. As long as WiFi offers more bandwidth than most people's ISPs, I think you can kiss that RJ45 port goodbye without upsetting too many folks.

Great reviews like this are why I love this site. Super thorough and interesting on the tech, and, interesting thoughts on practical stuff too.I prefer Windows, but have been wanting a secondary Mac for a while for the heck of it. I'm SUPER torn on what to get...
The 11.6" almost seems perfect, since I can throw it in my bag with my main notebook and be okay-stick it on my desk without too much issue. But...if I ever actually used it as my primary system, the 13.3" one would be a lot more usable. And at THAT point, the 13.3" Pro is a lot more usable, and at THAT point, the 15.4" Pro isn't much larger, and completely destroys it, and of course could be my main system...
Sooooo you see my dilemma ;)
Heh...maybe I should just go with the 11 since I'm not planning on using it as my primary.

"All three parts support Hyper Threading and Quick Sync, although the latter remains mostly unused in OS X. "Quick Sync is used by iChat HD, is it not?
The other natural client for it would be AirPlay. My guess is that, come iOS5 in September, we will see AirPlay on SNB macs beefed up to be able to stream any content (not just h264) to AirPlay devices by doing the transcode transparently on Quick Sync.
The third obvious sort of client would be a library that third party apps like HandBrake would get to. What's the currents situation now --- do you need to be root to get to QuickSync or can any app use it?
My guess is that we are facing the constant problem of new "weird" hardware --- it never comes virtualizable in the first iteration, which means that there is ALWAYS the problem of how to mediate access. And we generally see the same pattern
(a) A single app that is allowed access.
(b) Some sort of library that provides its own mechanisms for mediating access.
(c) The hardware (FINALLY) becomes virtualizable.
Apple is currently at step (a). Getting to (b) is never completely trivial (in spite of the claims of no-nothings in blog comments), at least if you want to do the job properly. You have to consider questions like --- do you use a reservation model, or do you simply provide notifications when you want to grab the hardware away from a user? How easy is it juggle state and provide something that looks virtualized? etc etc.
And there are ALWAYS, at least in the first gen, weird hardware interlocks that make life more difficult. I know nothing about QuickSync but I would not be surprised if, for example, using it has implications for using the main GPU, meaning one more thing that has to be balanced in the attempt to make it used more generally.
Can someone from the Windows world (who understands these issues, and has something more useful to say than "Macs suck") tell us how QuickSync is used in the MS world? Does MS provide a general purpose library, and how does the mediation model for that library work?

Oops, my bad. The Macbook Airs apparently do not have an HD camera because it can't fit in the available depth of the thin screen. So no iChat HD on these models.I think the rest of what I said, especially about AirPlay, still stands.

The sharing/scheduling of the GPU enginers by multiple client applications on Windows is mediated by the OS as part of the WDDM driver model dating back to Windows Vista - QuickSync is no exception. This means that we are already at c) on your hierarchy on Windows with multiple client applications able to easily share the GPU for encoding.Moreover, Intel has a library already for this - see http://software.intel.com/en-us/articles/media/
The media sdk library provides an API that applications can use to perform encoding and decoding. If run on a system with QuickSync hardware support and drivers, the work is routed to the GPU. If not, the library offers a CPU fall back path. This allows ISVs to write their application once - it will just run faster on Sandybridge systems.
I don't know enough about Apple OS and graphics driver model to comment on how hard it would be for Apple to get to the same level.

Thanks for the great review. I throughly enjoyed your review but I feel like one thing is missing.In fact, for a laptop review, I really want all the sites to start devoting some time and even creating a method to measure the heat that laptop brings on. We have to create some type of way to measure(benchmark?) the heat index as I feel like how hot laptop gets under certain circumstance is critical factor.
In fact, I had to trade in my 15 inch mbp since it was just getting too hot.

"This is what Thunderbolt was meant to do. All we need now is widespread adoption, more accessories and a standard for external GPU form factors."AND device manufacturers who are not idiots. In particular, where are the TB hubs?
The device the market obviously wants is a TB to USB3 hub ---
two TB ports, four USB3 ports --- and yet we still have not seen this.
I'm sorry, Sonnet, but this would be VASTLY more useful than your EN and FW800 bridges.
WTF is going on?
