I know you are primarily addressing mobile devices, especially the iPhone, but, the iMac and their OS has gone down the same path — into the shitter. It was after Jobs death, but, the last OS I really liked was Mavericks and it is no longer supported by Apple. El Capitan was atrocious. The cats didn’t have 10 lives and died with Mountain Lion (I also liked that OS). They have tossed out the concept of durability for planned obsolescense like every other tech company, because if something needs to be updated they can see more profit. Greed has rotted Apple to the core.
