There is probably more variance in the distance the device is held than for desktops, where for the majority of users keyboard usage roughly determines how far away the screen is. \r\n\r\nShould we be trying to define this or are there too many variables (e.g. far more mobile users will be using devices in widely different lighting conditions) to make this useful?
