No, she was lazy, pure and simple.
Because Apple PR was the ONLY source she ewas using to get her information.
And that is sheer laziness.
"Apple PR, I need to write an assignment, here's the information I need you to supply".
"Apple PR, you didn'ty answer me, I need this or I'll fail my module"
"Steve Jobs, I need the information by Moinday or I'll fail and your PR won't talk to me"
That's not "due dilligence", that's unmitigated laziness.
Had she been doing her assignment properly, the fact that ApplePR didn't give her the information she demanded (and looking at her extremely verbose opening email, I don't blame them - she waffles, she goes all over the place, she bores the reader to death; whatever happened to a clear and concise request for the specific details she was seeking? Had she done so, I bet they'd have given her a reasonable answer) woudl have made no real difference, she woudl have the information she sought via her other research efforts.
The lazy whining student demanded ApplePR effectivly write her assignment, then she bleated to Jobs when they didn't, then she gets stroppy when the Apple CEO doesn't write her assignment for her.
Lazy, lazy, lazy.
