Just a heads up Just noticed that on the New 13" there is no source of ventilation upwards at the screen hinge. On my 15" MBPr 2013 there's considerable ventilation even when placed on a bed or soft surface, as air flow is not blocked. This new model looks like all air flow will be blocked if you lay it on a soft surface like a bed. Just the way the screen is attached. I imagine it's that way with the 15". Not a big deal, just would be nice not to have to use something rigid under it at all times.
