I use my current 9.7" Pro for work all the time for taking notes with Apple Pencil. I will be upgrading to 1 of the 2 new Pro's, currently thinking 10.5 due to portability with the bigger screen. I have seen a 12.9 around the office and the size looks great for my use of note taking, with how close the size is to A4. Does anyone currently drag their 12.9 with them back and forward from the office each day? If so, how do you find that experience?
