I move it to the top since most window interaction is at the top: menus, minimize, close. That way my nose travels less. The inability to move the taskbar to the top is disappointing.
Your mouse, you mean? Otherwise you have some explaining to do :)
Next look at the top of the screen and then without moving your head, look at the taskbar. You can do it, but try it several times and it will probably start to feel a little weird. Your head is likely to want to move a bit, and holding it still takes effort.
YMMV.
