Once anyone gets to test the new MBA out (next month?), if you can please post the results on heat issues. Eg the initial MBA in many cases was only usable at 50% CPU/GPU (for more than a few minutes) due to heat issues. Does the new one fix it? If so, it is effectively more than double the speed.. more like 3-4x faster if that makes sense. If GPU is much faster AND heat issues are fixed, this could be a huge performance boost..
