I recently purchased a "paperlike" for my iPad Pro (M4, if it matters).

I'll be honest, it has made the writing like 20% better, but the touching about 50% worse.

The feel of the screen is somewhat irritating, though it looks nice when the backlight is dim so I thought I'd go to Apple and check out the nano-texture.

All I can say is that subjectively, I liked it even less.

I have no idea how people can live with nanotexture on iPad screens.

That said, a consistent issue I have with my Macbook Air and my iPad pro is that the "peripherals" touch the screen. My Macbook ends up with oily cubes where the keyboard and its edge has rubbed up against the screen display; and similarly on the iPad I have a perpetual line where the smart folio has its segments.

I thought I had unusually oily hands and started washing more frequently, but that seems to have made the problem worse somehow. :\

I just keep a clean microfiber cloth in my bag and wipe down my keyboard and trackpad from time to time. It really cuts down on getting the screen dirty from the other side of the laptop.

There's honestly not much you can do to prevent the "oily cubes" problem, especially if you keep the laptop docked often. You'll just have to clean the screen more often.

I've seen some people place a keyboard-sized microfibre cloth in between the keyboard and display but I'm not sure how well that actually works in practice. It might cause other issues.
