So, don't ask about SMP - ask about multi-processing, as SMP is just one type of multi-processing.
No, do. It's quite important.
Indeed, the difference is fundamental!
It's like apples and oranges, both may be fruit but they're not at all the same, not even similar.
The point is that when you have been selling $3.000+ HW/OS combos that has a pronounced SMP specification as one of the selling points (and also plans on selling others in the future), playing with words like this won't cut it.
An "Airborne stone falling towards the ground" is very far from "Hovering", both may be "stone-in-air", but while a "hovering stone" can be really useful and give a
general overall performance improvement to the system, an "airborne stone falling towards the ground" will very much less so...
This
DOES matter, the difference
IS important! So, don't ask about multi-processing - ask about SMP!
