Why the heck can't they build a 32-bit subsystem on top of the 64-bit windows? I'll ignore the fact that Linux does this fairly seamlessly, and instead focus on the fact that this is exactly how MS made the jump from 16-bit to 32-bit. The fact that they did not do this with Vista is shocking. How on earth did they craft an operating system that uses 10x the resources of its predecessor, but appears to offer nothing in the way of new features, save for a security setup and UI that was state-of-the-art in the late 90s.
