Did they fix the wavy/jittery diagonal lines issue discussed in the thread below? I can't find anything indicating that MS ever fixed it where the SP3 is concerned, but maybe they did with the SP4. I was very disappointed with the SP3 and returned it for a full refund when I discovered that I couldn't draw straight diagonal lines, something that I can easily do with my old Intuos 4. If they have fixed it with the SP4, I'll definitely consider the SP4 over the iPad Pro which even if the pen... err... pencil... turns out to be perfect, is going to be severely lacking in the software department vs good old Windows.
