> One answer is that people are just more sensitive than we give them credit for being. A 9–10% drop in weight may seem like a small amount to our brains but a large amount to our hands.

This has been my experience. I finally upgraded my Garmin Fenix 3 watch to a 7 (titanium). The 3 weighted 82g while the 7 is 73g. You would think the difference is negligible.

You would be wrong. It changes everything. I used to be extremely conscious of the presence of the 3 on my wrist. With the 7 I forget it, I don't even feel it anymore.

Honestly I would make a strong generalisation here that in matters of dexterity, small changes are profound.

The "jump" in phone size from the iPhone 5 to the 6 was extremely jarring (and the 12 mini) to me, despite being "only a little bit larger" than the 5.

I think our hands are so used to fine motor movement that small changes can have substantial effects.

Its interesting that the weight is such an issue. I have 13 pro it weighs a lot and i love it and the case actually adds some weight. Cant name all the reasons why i like it ( just a feeling i guess) but one reason is that i know for sure when the phone is in my pocket and i didnt forget it.
