I believe there should be two versions of Windows, a home version and a business one. Maybe put there Visual Studio software in that package, give it some real benefits for businesses.
As far as I can see there is only 2 PC versions (+ 1 mobile version) of Windows 10 available. From
http://www.microsoft.com/en-gb/windows/windows-10-specifications regarding upgrade versions it indicates...
* Windows 7 Starter -> Windows 10 Home
* Windows 7 Home Basic -> Windows 10 Home
* Windows 7 Home Premium -> Windows 10 Home
* Windows 7 Professional -> Windows 10 Pro
* Windows 7 Ultimate -> Windows 10 Pro
* Windows 8.1 -> Windows 10 Home
* Windows 8.1 Pro -> Windows 10 Pro
* Windows 8.1 Pro Student -> Windows 10 Pro
* Windows 8.1 Pro WMC -> Windows 10 Pro
* Windows Phone 8.1 -> Windows 10 Mobile
I do wonder whether a non-desktop edition for tablets would beneficial for more basic tablets. That said too many different versions might complicate things. I also agree that I hope the two different control panels will be merged to be less confusing.
