The reason for the popularity of mid-sized displays is that this size is reasonably easy on the eyes, often allows high resolutions and thus offers rich details on the screen, yet does not consume too much power and the devices can still be reasonably compact - simply the standard compromise.» To find out how fine a display is, see our DPI List.
A laptop with this weight is comparatively heavy and less designed for mobility than for use at the desk. Therefore, the devices tend to shine less with battery life than with a large screen and higher performance.
