Never mind Steve Jobs
Has anyone asked HP? They spent a large part of the 1990s trying to convince the world that touchscreen interfaces on PC monitors were the way forward. The world, I recall, quite rightly laughed at them as PCs, as then configured, worked much better with mice and keyboards and this holds true today for the tasks for which typing-oriented PCs are used. Browsing-oriented PCs, such as tablets, do work much better with a touch interface, as do specialised devices such as medical monitoring kit where HP did turn their touchscreens into an advantage, but if you need to type anything of any length then I'd much rather have the appropriate interface. Never mind writing a novel, how about coding a decent sized lump of C++ using a touchscreen? Mouses and keyboards for courses.
