Thermals & Power Consumption
Both the 11 and 13-inch MacBook Air use the same 45W MagSafe power adapter as the 2010 models. To get an idea of how much power the platform as a whole uses I measured power using the same power brick and a fully charged battery on all three MBA systems (2 new, 1 old). I chose two high-load scenarios: Cinebench R11 and Half Life 2 Episode 2. The former is a purely CPU load while the latter is a good mix of CPU and GPU load.
Peak power consumption has gone up significantly since last year. The 11-inch MacBook Air draws 35% more power under full load compared to its 2010 counterpart. In Cinebench R11 however, the new 11 is over twice as fast as the old one. A 35% increase in max power for a 2x increase in performance? I'll take it.
Overall power consumption isn't too bad. You're looking at under 35W for full load on the 11 and around 40W for the 13. Neither exceeds the maximum power draw of a 13-inch MacBook Pro.
How hot are the new Airs on your lap? For the most part they aren't too bad. Under a light load the fan won't spin up and you won't feel more than 31C on your lap:
It's under load that these things can get warm. If you're just measuring surface temperature then the new 11 can hang with the 15-inch MacBook Pro:
The 11-inch MacBook Air actually has it the worst. With a more cramped chassis things seem to get hotter more quickly in there compared to the 13. However max temperature is no where near as bad as the 15-inch MacBook Pro:
Overall the thermals seem to be in line with a 13-inch MacBook Pro, despite being confined to a much smaller chassis.

There is barely any difference between Elitebook models to talk about. Nor is there anything particularly special about them. Just another Windows clone made and supported a little better than what HP sells at Best Buy. Given that, it was covered quite well.OCedHrt - Thursday, July 28, 2011 - link
This is so last year. This is not even what I got in my Sony Z last year. For $1600. 2.4 ghz i5 (520m), GT 330M in 3 lb chasis with internal dvdrw. And that was bottom of the line. Not to mention I got mine from MSFT with 40% off.This year: http://store.sony.com/webapp/wcs/stores/servlet/Ca...
Of course this one costs way more, but still worth a though.

lol yeah. Sony is the only brand that has even more ridiculous pricing than Apple. You say it yourself 40% off. And in this case I say apple's pricing is very competitive and I'm an "apple-hater". Never owned a single device from them, not even an Ipod.The new base model Vaio Z will also be about 40% more expensive at half of the SSD capacity.
Anyway, I would have already bought it, if it was a windows system.

I wouldn't say Sony's pricing is ridiculous as you're paying for absolutely cutting edge tech whereas with Apple . The previous Z series may have been pricey but it featured a 13.1 1080p screen (genuine 1920x1080), up to an i7 dual core processor, quad SSDs in RAID 0, dual graphics graphics cards (one integrated, one discrete), blu-ray writer which even Apple's 17in machines couldn't match but was smaller and lighter than Apple's 13in machines.I have the Vaio from the previous generation (Z5) which has a C2D 3Ghz processor, 13.1 1600x900 screen, dual 128GB mSSDs in RAID 0, blu-ray writer and integrated & discrete graphics cards which again Apple didn't offer anything even remotely comparable. Speccing up a Macbook to the maximum level put it far above the Vaio in cost but far below in spec with just a 2.6Ghz processor, DVD burner, single graphics card and low resolution screen.

Kids, read the review and learn something before commenting. No Sony has this proc in it yet. Also learn something about cpu speed in different processor models. Finally try to understand that this laptop is meant to be super thin and lightweight which the Sony is not. It is also top quality construction support and uses a modern OS.OCedHrt - Tuesday, August 2, 2011 - link
The sony from last year is nearly the same weight at 3.1 lb with an internal optical drive and the new one this year is much lighter at 2.5 lbs with external.The Sony Z specifically do not use ULV processors for maximum performance:
Intel® Core™ i5-2410M processor (2.30GHz) with Turbo Boost up to 2.90GHz
Intel® Core™ i5-2540M processor (2.60GHz) with Turbo Boost up to 3.30GHz
Intel® Core™ i7-2620M processor (2.70GHz) with Turbo Boost up to 3.40GHz
The base processor already matches the top of the line Air processor in turbo and far exceeds it in other conditions.
So to recap: Sony Z from last year (Z11-Z14) is already super thin and light weight at significantly faster performance for same cost, and sometimes cheaper when Microsoft Store has a crazy sale.
Sony Z for this year Z21 is even thinner and lighter at even faster performance for a slight premium. Remember the lowest Z performs better than the fastest Air. $1969 vs $1599 gives you an external dvdrw and discrete graphics and usb 3.0. That's not a bad deal at all.
Keep in mind the fastest Z will kill the Air in performance all in the same chasis. And battery life from reviews indicate the new Z is on-pair with Air (4+ hours with a movie playing continouously).

$1600 was not 40% off. I got mine for $1100. $1600 is the retail price at B&M for the entry level model that I outlined (with 64gb x2 SSD).ViRGE - Thursday, July 28, 2011 - link
Looking at the specs, something doesn't make sense. They're using 35W TDP processors and claiming better battery life on a smaller battery than the 13" MBA. The math doesn't add up on that one.KPOM - Thursday, July 28, 2011 - link
Might Sony be including the optional "sheet battery" in that time?ViRGE - Thursday, July 28, 2011 - link
Nope. They break that out separately.
