Regarding the last point, pompyboard is very much a tablet or pointing device meant only for enthusiast osu! players from what I understand. No artist in the world needs a 8KHz polling rate tablet let alone 1KHz. Tablets from other brands are much better suited for drawing. While the basic idea of a rectangle you put a pen on is the same for artists and osu! players, the more detailed requirements are basically opposites

Basically:

- Pen click is useless for osu! or can just be digital, while artists would want analog pressure

- Buttons on a pen are actively detrimental for osu! but very useful for artists

- Smoothing on a tablet is more detrimental for osu! the more of it there is but absolutely necessary for artists

- High polling rate is useless for artists (they would have input delay due to the smoothing they need either way) but very useful for osu!

- Big tablets are useless for osu! players as they typically only use a 5-15cm area while they are very useful for artists

I think the entire point of something like pompyboard is to make a tablet just for osu!, which doesn’t exist right now. Meanwhile for artists there is already a whole industry of tablets available for them
