Apple's force touch trackpads are still wild to me. The fake button they used on the iPhone 7 and 8 wasn't particularly convincing to me, they kinda just feel like the bottom of the phone is vibrating. But the trackpads are so uncanny I almost didn't believe it wasn't moving until I tried clicking while the machine was powered off and it didn't do anything.

Also the fact that you can click in, and then do a further harder click that feels like a harder bump "in" than the first one, and when you start releasing pressure the click intensities reverse "out" as you'd expect. I usually use my laptop docked at a monitor with a full keyboard and mouse, but when I am undocked I find myself frequently playing with the trackpad click cause it's still so novel to me.

It's always fun to tell more casual MacBook users that the trackpad doesn't actually click cause they usually have no idea.
