I would think having a touch screen would sacrifice the resolution of the screen. Apple doesn’t want to go there, and I can see why.
Better inform Dell.
Wouldn’t affect screen resolution. Just more of a car of “why”. On phones and tablets, if makes sense. On a laptop, your hands are doing productive work on a totally different plane. Why move to a display on a different operational plane and mess up your display, when a trackpad, keypad or mouse will serve perfectly well? Seems a time and a place for a touch screen, and a laptop is neither.
