I have Chromebook with touchscreen. It's great to mix trackpad and touchscreen.

But after heavy use display became dirty because of human fat that remain on screen. I didn't notice similar things in iPhone/iPad however.

I suspect it's that phone and iPad screens do get dirty that way, but they're very easy to regularly wipe clean compared to a laptop screen, to the extent that it's not as noticeable that we're doing it.

iPhones and iPads have oleophobic coatings. Does your Chromebook?
