I use it several times a day. I use it in GoodNotes and the handwriting recog. is the best I’ve ever see nwith my scribbles. I use a combination of cursive, print and weird abbreviations. GoodNotes get about 90+ % accurate, impressive given the source material.
I use it to annotate PDF’s using PDF Exper.t I am using it to annotate e-books using some SW I am exploring that may replace the kindle reading app for me. I am using it to annotate web clipping also in the same reading app and I use it to create cartoons and drawings using procreate on occasion. I am slowly working my way through acouple of drawing text books and instead of pencile I am using the iPad and my Apple pencil and so far doing great.
The solution to the slippery screen is an appropriate screen protector. The one I got I can’t remmeber what it is but it was recommended here and I got it soon after I got my iPad so sometime in 2020. I’ll try to find it later…
found it the Moshi Best Screen protector
