I recently sold my late 2012 13 inch air for $1105 and bought a base retina for $1199. I have just done browsing and occasional you tube videos, and I noticed that the retina gets a lot warmer in only about an hour of use. I don't even remember my air getting warm under the same load. My question is now is it because of the power and resource the retina screen requires? I am now considering returning this for either the Haswell air or wait for the retina refresh. I will eventually do basic video editing and Win7 via VMware.
