Well I don't know what goes on at "marketing school" but here's my view: Knowing your audience seems really important to this discussion. Those of us with technical knowledge immediately want to know "what does it actually do?" But there are a lot of decision-makers without technical knowledge who might be swayed by their "general impression of the people they meet." This group doesn't necessarily care if they're in need of what you're selling. There's a spectrum between these two extremes and how you approach marketing is going to depend on your opinion of how the audience is distributed in this spectrum. If you believe there are more people toward the latter end of the spectrum then a more general, details-free approach may make sense.
