Earlier quoted context omitted.
When reading more than few lines of text on the screen, my hands do not tend to remain on the keyboard. They instead drift up the sides of the computer, making the screen closer than the touchpad. Not to mention, having the option to use both certainly doesn't harm anyone.
> They instead drift up the sides of the computer, making the screen closer than the touchpad. Isn't that uncomfortable?
Merely taking my hands off the keyboard is enough for them to move out and away, since I have to "swing" them in to use the keyboard to begin with. This leaves them inches from the screen in the best case, and nowhere near the computer in the worse case.
