The touchpad has a round shape because Panasonic has invented the circular scroll, and it is the BEST scroll on a touchpad. So in fact that small round shaped touchpad is MORE USEFUL than any big one. Also, there were complaints about the keyboard, but I can assure you that the Panasonic keyboards are the best, rivalling the ex-IBM ThinkPad (today "Lenovo") keyboards. Extremely quiet and durable.
