I am excited on having an ARM on a PC with Linux support but I never see Windows as an OS optimized for batteries beyond if they use ARM or x86. The Apple advantage continues to be a complete control of the device from hardware to the operating system, while the bloatware of Microsoft Windows makes an arbitrary use of resources.
This is not to say that Microsoft Windows is not an advanced OS, the problem is that it is not laser focus optimized.
I guess that's true but you can't make a leap like Apple did with their transition to ARM every few years. So it's good to see the competition catch up. And I'm perfectly happy with Windows laptops trailing Apple by a close margin instead of a 4 year gap.
