That's on top of everything else that comes with being a tablet, like speakers fucking up the cursor/pen relationship, edge jitter, jitter in general, parallax and so on.
Ipad Pro fixed most if not all of it by using bluetooth for their stylus instead of emr/ntrig.
Early Surface pro models have the standard halfassed emr because wacom doesn't want to supply their own competition.
3 and 4 have absolute garbage early ntrig that fucked up more things than it fixed.
2017 SP (or rather the new stylus, since using the old one is the same shit as 4) was basically a giant leap in quality and would be a decent tablet if it wasn't so overpriced.
Also, windows on a touchscreen is hot garbage, and PS is absolutely not designed to be used that way.
Either way, don't buy it, wait for the new model, which is probably due soon, or wait for the new Ipad Pro and use CSP for either option.
