Not sure why hardware design changes are a good thing on their own. The Apple Watch is well designed I’m not sure what I would improve except battery life and maybe taking the sharp edges off the Ultra.
The demand for change on its own is an odd one for me and not very Apple.
I really want a fridge with easily replaceable condenser, washing machine with easily replaceable bearing, and a Subaru with great access to spark plugs... You still live in era of 2003 phones where battery was accessible via a flap, but at the same time you want a top tier computer in your pocket and waterproofing. You people are ridiculous sometimes.
