I find mine close to useless. The pen is sometimes really inconsistent, to the point where the ink gets applied 1mm from the pen tip. Also, no canvas for pdf annotation, no split screen, no search in pdfs and notes, only tags, etc. It's strictly worse than paper for me.

Have you contacted support? I've had one for over 4 years (and used up 2 packs of nibs) and it writes perfectly, and much prefer it over the iPad.

That is likely a problem with that specific stylus --- have you tried a different stylus?
