I keep my soft RPi keyboard rested at angle on the close laptop which itself is at an angle on a laptop stand. This helps me to rest my wrists rest flat on the table while typing on the keyboard. But the trackpad (wacom) sits flat on the table causing me to reach out a bit and strain my wrists after a long use. The trackpad by itself cannot rest at an angle on the laptop like the keyboard due to the lack of surface area and grips at required places.
