Where exactly is it being marketed as a PC replacement? Show me one ad that says, an iPad Pro can replace your PC.
The 9.7 ad specifically says the iPad is where personal computing is headed. So personal computing is headed to a device that does not need or use a mouse.
I have an iPad Pro, and no it cannot replace my PC at all. Yes I use a Windows Laptop with a touch screen. And I barely use the touchscreen. Mixing interface mediums never works. But when I need a mouse, I go to my laptop, When I don't I stick to my iPad. If your work requires a mouse, then pick something that has a mouse.
So what you are saying is having a defined usage standpoint and an interface that answers to that usage standpoint is pride?
It's doubtful, Windows tablets will ever beat Apple's iPads. Namely because people don't like Windows on a tablet. Its not easy to use. Tablet mode on my Windows laptop is horrible. In fact Tablet mode goes so far as to discourage you to use a mouse on it. Even if it is possible to use it. So even MS with its mouse support understands tablets are geared to be used without a mouse.
So basically no, a mouse on a tablet designed for touch interface still does not make sense. And Apple knows this. It has never marketed an iPad as a computer replacement.
In fact it even suggests heavily using an actual computer to do stuff is recommended. Continuity is based on the premise that an iPad cannot do everything,
And if you need a mouse, Continuity makes it easy to continue the work on a computer that fits those needs.
In other words I can start on an iPad and continue on a Mac or even a PC, and then return to the iPad. making the usage of all the tools I need while working on
something, easy to access.
