InvisableShield has a product to cover the outside of the MBA. To protect it from scratches, and to give the case a tacky feeling, reduces chance of dropping. Assume the product is as advertised. My question is. When my MBA does processor intensive work it gets pretty hot. Photo processing, playing videos, etc. Will the invisableshield trap some of the hot air that warms up the case, instead of letting it radiate from the uncovered MBA? I like the protection angle, but not if it retards heat disposition.
