So, playing games in iPad Pro is faster than a MacBook Pro?
I give it two/three more years to apple to start rolling out MacBooks with ARM chips
The ARM chips are better in every way, if I'm not mistaken, than Intel's Core M chips that Apple is using in the New Retina 2015 MacBook (whatever you want to call it).
2-3 years seems too conservative. I'm guessing that in 3-4 months, Apple will refresh the entire MacBook line, giving the low end computers ARM and the high end ones will get Intel's Skylake.
