This person nails it.

The part about Procreate is really spot on. If you draw on the iPad, and I do, Procreate just dissolves under your fingers and pencil. It's like working with paper and pencil. Almost. And it has Undo. Tactile feedback would be nice, but I'm not sure what that means. Paper and pencil has great tactile feedback. Trying to describe it with words is an exercise in frustration. If you don't draw, or write with a pen, ever, then I'm at a loss to explain it.

But it's there nonetheless.

We've got a long way to go to really understand UI and UX. A long, long way.

Now, please excuse me while I go and tap dance about architecture for a bit...

> Paper and pencil has great tactile feedback.

I can try:

There's variation, paper to paper, pen to pen, pencil to pencil, they each present slightly differently. Write with a ballpoint on some receipt paper, then write with a fountain pen on some smooth, low absorbancy paper, then whip out one of those green engineering notebooks with a mechanical pencil.

For each task with a physical writing utensil and paper, you get a distinct experience that connects you physically to the task.

Once actually writing, there's a sense of finality, even the erasable pencil leaves a mark. Your movements have consequence.

Then there's the persistence. A piece of paper doesn't timeout to the lock screen. It's there, all the time, using zero energy to continue to exist. You can prop it up on your desk and forget about it until you need to reference it. If you're constantly going between two pages, you can lay them side-by-side without reducing their size.

I've always found writing/drawing on a tablet to be frustrating. It feels like I'm looking down at a notebook through a toilet paper tube, like I can never see the full picture. I used a wacom tablet with a chromebook and Xournal for years to take class notes. Something about disconnecting the stylus from the screen fixed those frustrations for me, like it took the expectations of paper away and provided the expectations of a pointing device.

Modern Mac trackpads don’t really click, they vibrate upon sensing a certain amount of force, and the sensory illusion is good enough to be indistinguishable from the real thing.

I’m only suggesting this tongue-in-cheek, but perhaps there’ll come a time when the Apple Pencil can micro-vibrate in such a way that is so convincing it will make you feel as if you’re dragging it on paper with configurable roughness.
