As I had reported in an earlier post, my earlier Air (rev. B) would get unbearably hot and slow down to a crawl, especially when I watched video. I am happy to report the new Air (which I received this afternoon) can handle video MUCH better.

The fans do kick in, and the machine warms up, but no way near as much as my older Air, and I don't see the machine slowing down, in spite of the video playing. This is exactly what I was hoping for!
 
I see no contradiction. For me, the iPad, being a slate tablet, was a better mobile. Also, I read a lot and like scribbling down notes and ideas; the iPad perfoms these tasks better. That doesn't mean that the netbook wasn't a good mobile.

Fans kick in a bit more often during high 3D use

thanks for the feedback on the new Air's temp compared to Rev B and C.

this news about the fans are discouraging. my fan on my rev B is practically running constantly so for me there would be no way for it to kick in more.
 
I bought the 13 "ultimate" version today (2.13 GHz, 4 GB) to replace my rev C MBA. Fans kick in a bit more often during high 3D use, but it runs much cooler. My old MBA sometimes got almost too hot to hold in my lap; no such problem with the new machine.

So sometimes louder; always cooler.
I want to get a 13 inch 2.13Ghz MBA with 4GB of RAM, too. Where did you find one? I didn't want to order from Apple online because if I am going to have to pay full price plus sales tax I want it now. The person I talked to at the OKC Apple Store said that they will not be getting the 4GB models in stock. Best Buy doesn't stock the 2.13Ghz MBA and none of the online outfits have it yet. Anyway, glad to hear that you haven't experienced any heating problems.
 
It's definately cooler I think this is mostly due to the new exhaust design. You would always end up blocking the old vents unless it was a on a flat surface.
 
finally a data test, new air can get just as hot and louder

External Temperatures and Noise
The old MacBook Air chassis had a few dozen slits cut out of the aluminum for ventilation. The new MacBook Air chassis hides the ventilation slits between the base of the unit and the hinge. You can’t see them, but they’re there.

The slits are smaller than they were on the old chassis, which means moving air through them at the same rate sounds louder than before.

The 13-inch Macbook Air under Load

The surface temperature of the new 13-inch MacBook Air easily gets as high as the 2008 model. I measured a peak of 38.9C (102F) on both the 2008 and 2010 13-inch models. The 11-inch never broke 38C (100F).

Even casual use can ramp up temperatures pretty quickly. Just having a few websites open in the background that use Flash or other CPU intensive elements can slowly cause the MBA’s internal temperatures to rise. And now you’re beginning to see why Apple doesn’t install Flash on these things by default.

The danger zone is the upper left corner of the system, near the hinge. There’s only a single fan that cools both the CPU and GPU in the Air’s very tight enclosure. This is where that fan sits.

Ι would wait for a more reputable source to review it first in terms of heat, many of the notebook specific sites on the web that run some good tests on all models.
 
I haven't played any video on my MBA yet but for everything else, including running several Windows apps in Fusion's Unity mode, simultaneously with several OS X apps, the temps on the MBA are significantly cooler than they usually are on my MBP running the same apps.
