Indeed this is true. The version that ships with the 2011 MBA is 10.7 build 11A2063, not 11A511. The build on the MBA likely contains the drivers for the new chipset, graphics, and Thunderbolt drivers for the MacBook Air. Also Bluetooth 4.0 drivers.

Well I've been using the i7 for a while now and the fan does still run. At first it was dead silent. But now with Safari and mail running, it is spinning. I'm starting to wonder if it's because of the i7 will run hotter vs. the i5??
Can you quantify what you mean by the "fan does still run"? The fan will always run. Normally it runs around 19xx - 20xx and is inaudible.
Can you post some screenshots of your Activity Monitor so that I can see which processes are hogging your CPU and also your temperatures when this is happening?
I haven't had a chance to check yet. Just busy doing a charge / discharge cycle to calibrate the battery meter and I haven't paid attention to exact battery life.
The main thing I care about is can I keep it on my lap while this is happening. I see in the same screen shot that the enclosed temps are around 32C? So maybe 90F is that to hot to keep on your lap?
I'm coming from a returned MBP as I couldn't have it on my lap for doing things like skype, netflicks viewing, having a VMware guest in the background.
At that temperature in the screenshot the enclosure is pretty cool to touch and to have on your lap. When I had the CPU at around 70 C, I had it on my lap and was wearing surf shorts so they are pretty thin. It wasn't uncomfortable, but I am not sure how one would feel after prolonged use. One thing worth mentioning is that the keyboard does not get as hot in the top left corner as other Apple laptops I've experienced so that's a big positive.
hmm I guess its going to be one of those things to test. I could have the MBP on my lap at 180F(cpu) but in the end didnt want to. lol
I was kinda hoping this would be cooler as the processor was toned down but maybe im wrong. What areas would you say are hot? The bottom back center? Only were the air is coming out? (below the mac name?) And what temp is that heat ruffly?
The most heat I could take was about 60c or 145f(cpu) thats why I ask. If all that cpu temp comes though the case I could be retuning this one too.

I must admit that I didn't take much notice of where the heat is coming from on the bottom. I'll play around this weekend and give you some more definitive answers.
This was actually my biggest gripe with my old MBP. The top left corner used to get too hot to work on comfortably, even when I was just writing some code in Xcode, had a couple of utilities running and Chrome with a couple of tabs.
After a couple of hours it would become so unbearable that I ended up using an external keyboard. Tab, Q, W and E were the worst culprits, especially since I tend to tend to rest my fingers in that area
This seems much improved. Even when encoding the top left of the keyboard stays reasonable to touch. It seems to me that the heat has been relocated further to the top left corner away from the actual keyboard.
Just an update on "heat"
My 13" i7 stays cool to the touch and is comfortable to use on my lap even when the CPU is up to 80 C. It also stays silent until I encode a movie or do another similar CPU intensive task.
I've just been busy setting things up, installing Xcode and so forth, whilst holding it on my lap. The fans have remained silent and stay at around 2000 RPM. I also have a couple of tabs open in chrome (with flashblock).

something a bit scary regarding the SSD performance here:

I just ordered the mba 13'' i7 with the 256 SSD - hope I will get the Samsung not the Toshiba one...
Others with the mba 13'' i7 do you all have the Samsung SSD like theSeb and Apple Expert ? ??

When i use handbrake my MBP15 2.0 quad core temp goes 77 c while MBA i5 1.7 goes 93
Both max rpm fan
Mba one fan
Mbp two fans
I can confirm that I'm on a 2011 MBA and my build is not the 11A511, but the one in the pictures.
