> What if I told you that Microsoft already had an operating system that did all the things you are trying to do, and it’s fully debugged, with video drivers, a graphics library, a dialog manager, a scheduler, a protected mode manager, and input methods. And it has a fully staffed support team.<p>I thought this was going a different place. Surely if you want to run an operating system, running Windows 95 itself would make more sense - then you could e.g. use the same drivers for setup that you're going to use in the real system.
