I have the RM2 and it took them one and a half years of me owning it until I could draw straight lines. I still can't search in notes, even after converting them to text. If I don't annotate everything I write with tags, then I'll have a hard time finding it again. The screen is imprecise, sometimes the line appears 1mm away from the tip of the pen. Their synchronisation service costs monthly, I think 3€? I'm simply underwhelmed, especially for this price. The Supernote would have been a much better choice for me - now I'm looking at the Samsung Tab S9 series for real note taking.
