> Instead of trying to shoehorn Linux into Windows, they could have launched another product with some of the ideas here. Then Windows 10 would not be in limbo (in terms of UI and features).

You have cause and effect the wrong way there: Windows 10 is in limbo precisely because MS have acknowledged that massive new OS rewrites every few years isn't cost effective. Not because Microsoft can't work out how to ship a new OS. There was a press release about how Windows would adopt a different release cycle around the launch time of Win 10.

I don't understand why you think Apple or Microsoft fragmenting their install base would be a good thing for business.
