Of course they're interleaved and they aren't mutually exclusive. So, for an overly simplistic thought exercise, let's say "form vs function" is an analog dial that runs from 1-10 (1 being "all function" and 10 being "all form"), Jony Ive's goes to 11 (and that's where in an admittedly exaggerated for effect my opinion sits about the past MBPs, the MBP has been before this model), and now, we're somewhere back at a 4-5 so it seems really shocking to some people (calling it brackish, thick, etc). Maybe all true, but we're more in a reasonable middle with this product in the gamut of form v function and it seems extreme or binary, when, really, it's just a return to a balance.
Remember, this all exists within the context of our current understanding of physics and what's possible with commercialized technology for a given market price: so all that is actually part of "form vs function" that isn't binary, but definitely an analog knob if you really want to simplify the analogy.
Like I said, if you want form *and* function and don't believe that they do actually trade off in product design and many of these (not all) are immutable (until significant innovations in materials, physical science, etc continue to evolve over the course of years): you're dreaming and/or fooling yourself about physics & economics.
