Hi, i really don't get people not using a mouse, its faster along the page, les movement needed, and I'm no banging my laptop to get on or change things, as for touch screen, you try as you might to keep the screen clean, not an easy task, then you get some sweaty greasy jamy guy who wants to rub his fingers all over it, crazy never got touch screen,
Because a lot of computing tasks are mostly about manipulating text and/or issuing commands which is just much better done with a keyboard than a mouse. You keep your hands on the home row of the keyboard and can do everything directly without moving our hands. And where you are doing this for many hours a day (i.e. a job) you are just going to get incredibly proficient at this very quickly in the same way a joiner gets very good at hammering in 6" nails. This applies in generic applications like word processors and spreadsheets and more specialised things like engineering or graphics programs and so ends up being an important thing in many professions.
In this context picking up your mouse to select a menu option and clicks a few things is incredibly disruptive and very slow.
