The targeted consumers of the Prime are users in scholastic institutions who will sit exams;

Such users require an easily mastered (colloquially intuitive) operating system.

Are the two statements

1 Contradictory, meaning if one is true the other must be false;

2 Contrary, meaning at most one can be true;

3 Sub-contrary, meaning at most one can be false;

4 Equivalent, meaning both have the same truth value?

What I'm angling at is the discrepancy between the justifications of the Prime's limitations & the incredible difficulty of getting the machine to articuate my wishes agreeably.

I think none of your options 1..4 apply.

Both statements can be true at the same time.

They are not equivalent: the first one identifies a group, the second one asserts a characteristic of the identified group (but that characteristic does not necessarily uniquely identify the group of the first statement).

I think the questions are:
1) does the Prime live up to the those statements?
2) when they do sit some national exam (of any of the countries where it is approved for such), will there be embarrassment for HP if the Prime pops out a wrong answer?

Best regards.

Your 2nd sentence discounts 1 & 2.

Your 3rd sentence discounts 4 (Although I doubt your reasoning).

You haven't dealt with 3.
