because cpu need to support old software 8086, 80386.  it waste power

OS development - some company such at handheld and embedded application pay attention to squeeze every juice of power from every line of code so that they will do performance and power usage benchmark before add to OS.

some company just like MS pay attention to GUI / user friendly direction so that you will see MS OS always fatter and need more resource in term of cpu. hdd space and memory than other OS in size.

原因亦包括太多背景服務同程式, 以及windows既power management都冇mac optimize 得咁勁

佢係指出, 佢部NOTEBOOK O係WIN7下, 運行左104340秒都只係食左2022480J, 即係一秒只係用19.38W
(好省電)

咁講真, 我部T42一秒連牛都係食12,3W遮
但MAC 既電源管理, 同資源使用率上都比WINDOWS 優勝, 係毫無疑問, 而輕量版LINUX好似PUPPY, 配合LINUX既POWER MANAGEMENT TOOLS, 可以比MAC更勝一籌
