Windows is like a Hummer - hugely expensive, requires an engine the size of a planet, and delivers very very average performance.
Who REALLY needs transparent 3d windows? I'd rather save a few GB on the install and most of my CPU's power and just have a blank page with some icons on it that sodding well work when you run them, and don't require a PC with more power than god just to run a very average game because most of the power is being sapped by the OS.
