The Pen Tablet line of tablets does not have Touch Input of any kind. Since there is no Touch Input, there is no need to worry about palm reject issues with the Pen Tablet. 

When Xencelabs was in the concept stage of creating the Pen Tablet, we talked with Professional Artist and Design Studios to get their input on our tablet design. Two things keep surfacing as issues.

  1. No need to have touch. It gets in the way.
  2. Hand fatigue when drawing for long periods of time.

Out of that came the Pen Tablet with no Touch Input and one that includes a Palm rest to help with hand fatigue when drawing for long periods.
