Wacom

If you don't know Wacom, you're living under a rock.

Wacom is the leader of the drawing tablet market, and the oldest as well. They produce pretty much the best tablets in terms of digitiser performance. However, lately (since 2015 or 2023 depending who you ask) they've been producing some some questionable tablets.

Their 2023 Wacom One (not to be confused with One by Wacom) lineup has been quite bad, with tablets that handle pressure terribly.

They also partner with Samsung, providing EMR technology for S-Pens. They also partner with many laptop brands. You can find their AES technology in many laptop models.
