For laptops you have to remember that, at this time, the biggest power consumption (for screens bigger that 10-12") is the LCD (mainly his backlight).
So, what you're gaining putting in an high-end ARM against a "low-power" X86 is a portion of the total power consumption of the laptop.
Why choose ARM then?
When the screen real estate is smaller than 10" or the size of the CPU+Logic Chip is important (take a look at the size of an Apple A4 against an Atom+Chipset). And when you don't have a large codebase already available.

The new AppleTV is a good example of this, the usage of the A4 is a no-brainer whatever Intel CEO says: http://www.businessinsider.com/intel-ceo-steve-jobs-took-a-s...
