OMG! How did you manage to install Snow Leopard on Macbook Air 2012!? I'm very curious to know the method.

If you still have the DVD then I guess you can just pop it in your super drive.

Snow Leopard doesn't have the drivers for new hardware.

One data point doesn't mean it's a design flaw. Most people aren't going to take their MBP offroading, so why should they make compromises just to serve this small, but now vocal minority?

Why would they have to make compromises? Both possible solutions for this problem doesn't require any compromises at all...

Hm, this might explain why my 2011 Air is occasionally on and hot when I pull it out of my laptop bag, too. I only started noticing it after the Mountain Lion upgrade, so I figured it was more likely something to do with their crazy new sleep mode, but hey, perhaps it's a combination of factors?

I don't think the Air can fully turn on in clamshell mode, unlike the pro. This is (I believe) because the air uses its body as a heat sink.

I haven't seen this particular issue, but I have had a whole bunch of strange, likely firmware-related issues on my Retina.

For instance, sometimes the screen just won't shut off when trying to put it to sleep - Closing the lid and the screen/logo stay lit up indefinitely. Chrome and the integrated graphics card really don't play well together - it's caused an OS reboot 10's of times in the past month. Mostly, waking the computer from sleep takes a fraction of a second but sometimes it takes ~20 seconds to show the screen.

I would guess that all of these are related to the integrated Intel graphics chip firmware/drivers being not quite baked.

BUT - in spite of all of that, this is without question the best laptop I've ever owned. It's also the first laptop where I haven't wanted or needed to use my iMac anymore. It really is finally a true "desktop replacement" that is totally portable. And I could never go back.

"Mostly, waking the computer from sleep takes a fraction of a second but sometimes it takes ~20 seconds to show the screen."

I've seen this as well, and it feels related to whether the computer is suspended to RAM (sleep) or suspended to disk (hibernate).
