This applies to all Mac notebooks: Apple Portables: Operating temperatureAh yes should probably make that clear 80% of the time I'd use my MB would be on my lap, so as long as its not so warm as it becomes uncomfortable on my lap through trousers I'm happy
The bottom of your Apple portable may become warm during normal use. If the computer is on your lap and gets uncomfortably warm, remove it from your lap and place it on a stable surface.
They can get quite hot around the rear left of the base, but not enough to cause serious concern. But anyone who says they don't get hot is a liar.
I can confirm that few MBA's I've had all get hot when watching videos on YouTube etc.
The person who said they are "like an ice cube" is clearly on crack.
I sound like a MBA user who confirms they can get hot.
I've used my 2012 MBA for several hours where watching YouTube videos was parts of that (Flash installed) and the bottom was only slightly warm to the touch, not hot at all.
Why do you think we would take your word above anyone else's?

The unavoidable truth is that they can get hot. There's just absolutely no disputing this fact or denying it. I think it's poor form to cheat the OP with an incorrect answer to his question.
