Your trackpad comment brought back a memory of 6 of us in a conference room.

We all had the same OS (NT) to the same patch level, same trackpad config, and same model of Dell laptop and every _single_ trackpad felt different. They weren't strictly "defective", but just wildly disparate physical feels and responsiveness.

I will give shout-outs to: 4th gen Kindles (has physical buttons and lasts forever), first gen iPhone SE, and Microsoft Mobile Mouse 3600.
