Not sure if everyone is aware, but the plan is for Haswell to be in every device, including phone. When INTC rolls out 14nm version of Haswell, it will fit in a phone. Imagine that, a desktop core in a phone! ARMH - wha yu got??!!
In the meantime, Atom chip (z2580 beginning of 2013) will easily handle the competition in smartphones...but Haswell is the platform INTC is betting on for the future and will replace all variations of INTC chips for consumer devices.
