Here's a subtle problem: An animation that looks "delightful" on the screens you have, might look pretty bad on a screen you don't have. For example, the author's animation for scaling a button looks fine on my M1 MacBook Pro, but jittery and sluggish on the crappy IBM ThinkVision monitor attached to my MacBook. See for yourself:

Are you using your IBM at its native resolution?

Does it matter? Some users will perceive it this way (or better or worse).

		It matters if you want to attribute the problem to the correct source.
