On the contrary to many other comments, I think this article is quite interesting. As a mechanical engineer, I know moment of inertia is very important for many designs, albeit often for more functional reasons than the user’s feelings.

It is a short and quickly written article with back of the napkin maths but its good enough (and what most engineers are doing at work anyway). And it reminds us that the spec sheet is not everything. It’s nice to have a lighter phone, but is it really what matters ?

It shows once again how Apple design teams are focused on user experience. I know they aren’t perfect and Apple gets a lot of criticism on HN (mostly deserved), but at least they are great on pushing the extra mile on this kind of things.

It reminds me of how much people were surprised about EV acceleration capability because they compared vehicles on HP, overlooking sometimes torque and often jerk curves.
