Phones are built for performance per watt. Phones are benchmarked. In the context of a discussion on Apple introducing ARM chips into the Macbook line, performance per watt is far more meaningful. For most users, battery life is the issue once minimum performance criteria have been met.
Will there be Razor laptops that last less than an hour on battery that can beat them? Sure.
Will there be people who complain that the Mac isn't fast enough when plugged in? Already happening: the recent Macbook Pros have had complaints about thermal throttling, that obviously slightly larger Dell with a decent fan doesn't have.
But Apple will build performance laptops, using ARM chips, and they will be faster than the equivalent Intel Macbooks if only because they aren't throttled.
