Because e-Ink is a very different technology from LCD (or CRT), and having anything that "scrolls around" would not be fast enough and energy efficient enough to be worth it. There's a reason that you refresh the entire screen at a time and don't just scroll a line at a time with these devices: they use almost all their energy when changing the display. If you were constantly changing it, not only would it require a very different display configuration, it would use far more energy.
