Ok I just got finished reading this whole thread and took in all the info. I do work for Best Buy and have dealt with both very knowledgeable people and idiots. Thing is that most of the less knowledgeable people do a fine job of selling because 90% of customers know almost nothing. For those customers who know more than the employee, that particular employee trys to match up that customer with the more knowledgeable employee. Usually there are at least 1 or 2 people working in computers that really know what they are talking about at any given time (at least in my store). Basically what I am trying to say is that I do expect all employees to have a general knowledge of the products and services they sell but would prefer a more in depth knowledge.
On a side note, the Apple Rep in my store has a very good general knowledge of his products but not a very technical one. I was actually the one to show him that the 17" pro had one extra usb port over the 15", and I once heard him explain the dual gpu's in the unibody pro as giving more power to the laptop instead of being able to switch between them. (I didn't want to correct him in front of the customer though)
