This sounds like everyone here is about to get into an argument over hand position. I feel like the hand being positioned hear the bottom of the computer is the result of you knowing that you can scroll with your thumb like that. Wouldn't your natural position after using the keyboard be to just relax your hands which would put it right near the trackpad? It seems like moving your hands out to the side of the computer/table/desk is a self-fulfilling improvement as you most likely wouldn't put your hands there if there wasn't a touchscreen. There would be no benefit or convenience to it otherwise. On top of that, you'll most likely still have one hand resting near the keyboard for typing which further worsens the inconvenience.
