    Okay guys, these are my opinions. I'm posting this because I'd like to avoid some other people buying this with unreasonable expectations.

    Look closely at the vents on the macbook air. They are VERY close to the surface the computer sits on. This is fine on any hard surface, but it is NOT fine on anything soft. This computer will heat up on your lap, in bed, on any surface that isn't hard. The computer will sink down just a little covering all the vents. This by itself is almost okay (it got very hot) but what also gets hot is the top of the unit by your wrist wrests. It is VERY uncomfortable to use with the top heating up, even some heat coming from under the keys!

    Just taking a good look at how the vets are placed makes it common sense that any soft surface will cover the vents completely. Not a good machine for laps, bed, or ottomans. I hadn't noticed this before I bought it, just hoping some people think a bit about it....

    Your point is well-taken. Obviously, blocking the vents, like crossing the streams, is something you should not do.

    But is this the only reason you returned your MBA? Poor vent layout?

    I guess you've ever owned a Macbook Pro because they all get hot around the wrist wrests. The newer models less so than the first Core Duo versions. The Aluminum is especially good at conducting heat compared to the plastic MacBooks.

    I returned my car because it got too hot. I never changed the oil or fixed the thermostat, either. But oh well...

    My MBP doesn't get hot at all around the wrists. Depending on what i'm doing, sometimes it gets warm on my lap enough that i get sweaty. :eek:

    No, it's not the heat that bothered me, it's WHERE it was. I've never had a laptop heat up at the wrists (correct, I've never had a macbook pro) Usually vents are on the side, the air has no sides so it vents down. Just something to think about before you buy, something I wish I had and something that made it a dealbreaker.

    FWIW, Apple's been saying that for awhile now. :)

    My experience, I used my 1.8/SSD for at least 2 hours (maybe more) sitting up in bed last night with the computer on top of the comforter. Browsing the web and email, it never got beyond barely warm. The fans didn't kick up to high once. I guess my usage isn't pushing the processor. :)

    I've been using mine in all kinds of ways since Friday and I can truly say it doesn't seem to get 1/4 as hot as either my MB or MBP did in same circumstances. The absolute coolest running Apple laptop I've ever owned.

    Sure, I'm well aware of this. I'm aware that laptops heat up more on non standard surfaces. The difference here are those vents. Laptops tend to vent out the side or the back. With the way the air is designed, there is no side or back so they have to vent down. Most laptops get warmer, but no matter what surface they are on at least they can vent, this one cannot.

    I was well aware of this before I bought it. If you go to the ifixit site you can get an idea of what is going on with the ventilation.

    This model unlike the Macbook pro uses the case as a heat sink, apparently.
    (guy at ifixit says this, and that it's an new design)

    if this is the case, vent obstruction may not be such an issue. There is a fan of course, but exactly how the air moves is unlclear (to me)

    Of course the best way is to just test this. If the case is a heat sink then placeing it on a bed will get it very hot, but on you lap in bed it should be fine.

    I've been using this on my lap in bed and it's actually suprisingly NOT hot... (just slightly warm).

    You ate almost $200 if not more because it MAY get hot?

    That's entirely wrong. The aluminum is part of the cooling system on the MBP's, just as it was on the PB's and TiBooks (well Ti, in that case). If I put my MBP on a soft surface, but keep the vents open in the back, it will get very hot. It's part of the reason they can both a] make it 1" thick and b] make it relatively quiet (because they can keep the fan revs low).

    MBP's need to be on a hard surface, so when using it on a pillow or such, put it at least on a CoolPad under it to allow some airflow (as noted in a previous post "per Apple").

    I cannot for the life of me figure out how you think my heat issues with this laptop are hypothetical...

    "his by itself is almost okay (it got very hot) but what also gets hot is the top of the unit"

    Think you should have taken another for a try.

    The outside of my Macbook Air is at least 10ºC cooler than my Macbook under my normal work load. I don't understand where the heat issue is coming from unless you stuck a pillow in the vent.

    Same here. It seems to be a lot better than my CD MBP.

    Need to change my sig! YESSSS!

    What apps were you using to get it so hot? If you were just surfing it must be defective judging by everyone else's comments... The SSD should be even cooler!

    Easy fix for soft surfaces is one of the plastic or glass cutting boards.
