In my experience with the SP3, the N-Trig pen tracking was far inferior to the Wacom pen in the earlier Surfaces. The poor tracking made my handwriting unacceptably sloppy-looking. I'm surprised artists can use it, but maybe you use mostly faster and longer pen strokes?

As a side note, one thing I've noticed on hn is actually a lot more love for what Microsoft does right than I might have first predicted. That's not to say that it's all great all the time but level heads opinions seem to surface pretty quickly. I'm not in love with ms myself, but I really like and appreciate a lot of what they're responsible for, which includes the surface. Going to have to get one.
