yeah they tried to re-invent something that has been already invented, and failed (of course).
they should copy 1-to-1 what apple does, since it's a proven strategy. it's also proven that it's not a monopoly (in the us, at least), so it's a safe game to play.
It'd be nice to have consumer windows laptops that are as safe as macbooks, because Microsoft can enforce the presence of TPM and can drop hardware support when it deems necessary (because it's the only producer of consumer windows laptops).
The problem is, when OPENSTEP was announced as a programming system for the Mac OS, Bill Gates' answer when asked if Microsoft would develop apps for it was, "Develop for it? I'll piss on it." --- which some suspect is why Carbon/Cocoa were referred to as Blue Box/Yellow Box.
