How are they delivering the same services when the PC can't run Xbox One games which is its primary software and the Xbox One cannot run desktop applications which are the primary type of Windows applications? On Metro apps, the support on Xbox One isn't even there yet, and it's likely they won't run unmodified on Xbox One anyway; Microsoft has merely said they'll try to make porting easy. The PC also supports vastly more peripherals than Xbox One; you can't even use an Xbox 360 controller on an Xbox One!
I honestly don't understand the point you're trying to make: we're talking about two very different devices designed for completely different purposes. The idea of using Photoshop (real Photoshop, not the photo touch-up app that has "Photoshop" in the name) on an Xbox One is amusing at best. And I'm just using it as a well-known example of the type of application that's not supported by the console.
What about AutoCAD, Blender, 3DS Max, Cinema 4D, and others?
They would make horrible metro apps, I can't even imagine using them on the Xbox.
Face it, The PC is used for different things. Aren't these different OSes anyway? They might have the same core, but it is not 100% identical.
