Nice of her to send this to you/us, but still the justification of her background was unnecessary if the joke hadn't all started to a bunch of strangers like us. Her joke might have worked better had we /many of us knew her and something about her in advance. But we didn't.
Do any of us have to give a huge resume to each other here when we joke?
We're her potential customers, for pete's sake. Would senior manager/executive at Apple Computing pull a joke on millions of unknown, faceless customers? I think she's lacking business marketing judgement.
