I currently own an SP2. I use it every day for my work and among other thing, I record notes throughout the day in the form of job cards. My use of inking is basic but frequent and I really enjoyed the SP2 and still do. I then bought the SP3 but right away didn't like the handwriting nearly as much but figured I'd get used to it. Unfortunately I also found that the palm rejection was not nearly as good. This may be due to the Wacom EMR layer built into the screen or simply that on the SP3 the pen is not detected until much closer to the screen 1 cm versus 2 for the SP2. It is also aggravated by being left handed I think as well. In addition to these issues I would occasionally find it might not write at all. I should also note I use modern OneNote for note taking. Please only respond if you use inking frequently and have had experience also on earlier Surface models.
