Natalia explains the Surface situation:
Microsoft’s Surface PCs with Windows 10 can double up as tablets. Lousy tablets. A tablet so lousy it makes the iPad seem more as a gift from the digital hardware gods than the competition.
The Surface is not a tablet. Why does Microsoft think it is a tablet?
It’s all about differentiation. You cannot use a touchscreen on a Mac. Windows can, therefore, Windows runs on a tablet. OK, forget the fact that hardly anyone uses a Surface notebook as a tablet.
