Apple certainly puts out experiences that leave much to be improved but to be pedantic the word 'subpar' implies below the 'par'. If 'par' is set by Microsoft then Apple easily clears it.

Nowadays Chromebooks offer more design competition for Apple, and even historically Linux distros have had more ideas for Apple to learn from than Microsoft.

That's clearly subjective. What you will accept from Apple is unacceptable to others as garbage, the same as you dismiss anything from Microsoft.

>Linux distros have had more ideas for Apple to learn from than Microsoft.

And yet Apple just copied Windows Vista with their "glass" monstrosity that is universally hated and has been lambasted widely. Again, you may love that, but that would put you in the minority.
