Windows 8 promises to deliver superior user experience and power efficiency for applications. "Minimizing the power consumption of your PC while maximizing the responsiveness and utility (making it “fast and fluid”)" is probably the central theme behind the development of Windows 8.
Windows 8 also promises to use sensors to enhance display / screen performance by making it more responsive to "changes in ambient light, motion, human proximity, and location"
