Macs with ARM processors don't seem like a possibility. Intel Haswell processors are shown to have comparable Performance per watt which is expected to get better with Broadwell. ARM64 Apple chips are play for iPads. Current iPads are lagging on performance when we compare it to something like a Baytrail Intel tablet or a Haswell equipped surface tablet. There is going to be convergence point for Intel where a tablet with Haswell level performance with a Fanless chasis and 500$ price. Apple need to converge there to compete.
