WinM also has a really proven kernal that's actually pretty small and it's the same kernal that XP, Vista, Win7, 2003 and 2007 etc have.

Sure they share similiar style user mode APIs, but at the kernel level I think you'll find they share very little in common at all.
That statement alone points out how little technical detail you actually know about the platform.
