I've been going to Best Buy since it was Sound of Music. Rarely, if ever, did the sales person know much. They are droids and get paid as such. If they actually KNOW something about the product they should be promoted and moved up. They are like "gas pump attendants" we had in the pre80's. I view them (and most other big box retail service staff) as being there to tell me what aisle it's on, to move the ladder to get stuff off the top racks, and to prevent the other clientel from stealing the store blind.
