I use my pencil for writing on pdfs, handwritten notes, drawing and practicing my second language.
I love the pencil! It's what I had been waiting years for as I could never get on with any other stylus (I bought, tried and gave away a few). I love the precision and lack of lag (at least to my eyes and those of people I let have a go of my pencil). I'm not aware of the tapping on glass noise when I'm writing as I don't write aggressively, but sometimes when I playback a note in Notability with an audio recording, I can hear the tapping noise and am quite surprised.
Just opening the Notes app and doing some writing and doodling and erasing and messing around can be very therapeutic. Putting the pencil on an angle and 'shading' and seeing it actually look like the real thing on screen, can be a real pleasure. Running the highlighters over each other and seeing the colours blend like real life is incredible. You can make a mess, experiment with oil paints and acrylics, even finger paint and smudge everything in Procreate, and your hands don't get dirty. You can save a fortune on art supplies as you discover whether you're really cut out for oils/ pastels/water colours etc. It's also much quicker as you don't have to wait for the layers to dry. It brings a more level playing field to art. People who couldn't produce anything on an actual canvas before are given the confidence to try anything, mix media, learn and improve. Time lapse videos of your creations are fascinating to watch.
Your piles of notes can be stored neatly in the ether (poetic licence rather than a technical term). You can write in the margins, highlight, put sticky notes on them and then magically erase them back to a clean document if you want too.
Your pencil lets you doodle all over important documents in meetings and then erase them before any damage is done...
The pencil is amazing!
