Pressure and Tilt Sensing

Line weight and shading come from how hard and how steeply you press.

Low Pen-to-Screen Latency

Ink that trails the nib makes handwriting feel wrong within one sentence.

Reliable Palm Rejection

Resting a hand on the glass is how people write, so stray marks ruin a page.

Matte, Paper-Like Surface

Texture gives a nib something to bite, and it cuts reflections while you draw.

Layer-Capable App Support

Sketching over a reference needs layers, not one flat drawing surface.
