What does Windows 10 S say about the other versions of Windows 10? That they are unsafe, unreliable, and slow. This is a not a great marketing message.

I've been thinking a lot about Windows 10 lately, as you may know. And this system puts me in a tough spot. It is, after all, the future of Windows, an important step forward that positions the platform for the mobile first, cloud first world. But it is also, sadly, completely unusable today, a non-starter for virtually all users.
