Under the hood there's price discrimination on the Hypervisor and other services that regular users wouldn't use, but there seems fundamentally to be no difference in the interface between the two versions of the OS.
I'd assume enterprise customers (the real "pros") will have their IT department deal with removing all the crap and adjusting the group policy so the experience is somewhat productive. So Microsoft doesn't have to care at all about "productivity", and is free to bombard users with all the crapware of the worlds as long as there's some remote way to disable it.
The price was pretty stiff, so it looks like I got priced out of the reasonable default experience.
