Don't trust your sales people for relaying proper user input in product development. Why would I say something like that? Anyone old enough to remember the 70's? Burnt Red and Avocado Green were reported to be the colors that the market were demanding for kitchen appliances.  Usually it was a someone from sales who was voicing this wisdom.

I'll let you in on a secret. The depth of a salespersons insight into what "the market" is demanding is to repeat the product features that the last customer he talked with was interested in.
