    From Jason Snell's (MacWorld) review:

    ``Apple is making a big deal about saying that these new MacBook Airs have “instant on” technology. I haven’t had a chance to do a lot of testing, but it seems that what the company is talking about is a new power-saving mode. After it’s asleep for a while, the laptop switches into a super power-saving standby mode that lets the battery survive for up to 30 days. But when you open the laptop back up, it doesn’t show you a progress bar while it loads stuff—it just snaps back to life. Or so they say. I’ve been too busy actually using it to figure out all these permutations. Stay tuned.''

    The bolded part says that the MacBook Air essentially goes into deep sleep (or hibernate mode) after it's been light-sleeping for a while, so there's not really a need to indicate that it's sleeping. Unlike other Mac notebooks, which need a power button press to awaken from deep sleep (as a result of running very low on battery charge), the MacBook Air will automatically arise from deep sleep after the screen has been opened (detection done by hinge movement). Hopefully this explanation helps, and if not, criticize away!

    I also think that sleep is the expected behavior now so a light is basically useless. I almost never leave my MacBook off but when I do I don't even notice that the sleep light isn't on. I just open the lid and wonder why the screen is black. The iDevices don't have sleep lights because of the same reason.

    I'd expect to see the light disappear from further MB(P) models as they push more into flash memory and instant on.

    I found that with my previous MBA & MB, that if it's asleep and I take it to a cafe or to work in my bag, it sometimes wakes up even the the lid is closed.

    This is a problem since the Mac will then heat up in the bag and the fan spins (while being vertical) and essentially is awake and overheating.

    My worry with this new sleep is that it too isn't really asleep and unlike a iPhone (which I swipe to wake), the new MBA will still somehow wake...meaning I have to turn off everytime I carry it places.

    Thoughts??

    I don't think it's a problem because the MacBook Air uses a solid state drive, which means that there are no moving parts in the disk to destroy.

    It did get hot and the concern was not just the ssd but the motherboard, the ram, and the moving fan being vertical. My fan had to be replaced once (no biggie) but sheer fact that it woke was troubling and HOT :(

    No wireless (blutooth or wifi turned on).

    Oh right, the fan >_< Well as with any other Mac, the MacBook Air will suspend all activity when you tell it to sleep. The instant sleep feature comes from the fact that the Air is able to take advantage of the SSD's sheer speed to load back its original state very quickly.
