I wish these sales-type pages had a "click here if you're an engineer." The page would contain a buzzword-free, straightforward explanation of what the product's purpose is, what its major features are, and what interfaces are exposed for control and flow.

I have passed on countless products when evaluating solutions for having very flashy sales pages with no actual description of the product itself. "Improve your ROI! Decrease Downtime!" aren't features, per se, but potential benefits that can only be determined if the product is a fit, and I can only determine fit if I know that the hell it does.
