Don't forget that your scanner only has a single row of sensors, not a two-dimensional array, and that it only has to work at a single speed. Of the two, the fact that it's only a linear sensor is more important. You can put the extra processing elements, etc., alongside the sensor without having to worry too much how much room they take up. In a 2D sensor you're trying to put another row of pixels there.
