Once you find a comfortable location for your tablet you will want to affix it to the work-surface in order to maintain its exact position in relation to your monitor, aligning them to each-other along the same parallel plane. This is critical to learning, and mastering the necessary eye/hand coordination between your monitor and the tablet. If the table is moved or rotated even slightly you will need to relearn the necessary eye/hand coordination. You can affix the tablet to your desk with double-sided tape or museum putty.
