But, in animated media, "people" can include things like phones, papers, and books.

Apologies for missing this. I took the claim to mean not just animated movies, but animations of our devices. I am specifically remembering the silly animation that ubuntu used to have where a window would shimmer and shake as you moved it around. Or how it will "pop" onto the corner of the screen.

Windows that are flimsy are just annoying to me, which is why I would find the view that they are quality curious.

More realistic animation is typically described as more realistic. Not "popping and snappy."
