Right, also heat dissipation is a function of the processors. I don't think Intel has any processor offerings in the i5 and i7 families which will enable fan-less laptop design. Asus seems to have swapped the Core M processors with the i5 and i7 families in their latest Zenbooks. At 700$ this laptop is a steal.
