I work retail as a receiving manager and I'm the most knowledge person in the entire store when it comes to computers. Hell, I MENTION Tom's and Slashdot and all I get is confused looks. Anyway, here's the top ten reasons why "computer" salesmen in retail are the way they are:
1) Most stores hire the best salesman to be a computers salesman. Again, I've seen used car salesmen hired because they don't ask what they are selling, they just sell it.
2) All they are required to know is what the store carries. Asking the average retail person detailed specs about anything that the store doesn't carry is a mistake. Again, most only learn what they are carrying. I'm the same way when it comes to printers, scanners, most of the stuff save computers.
3) No training provided by the corporate offices. Most training is done on the sales floor.
4) If they do learn on their own time, they aren't paid for it.
5) Why would someone with a degree in computers work for $9 an hour?
6) All most learn is what the sales tag says and what they mean. Most have no clue about any detail specs about the machines.
7) Most retail systems don't tell you DETAIL specs anyway. I just learned that an HP doesn't use IDE opticals and doesn't have an IDE connection on the mobo anyway. Of course, HP doesn't tell you that.

8 - Most are they're just to earn a paycheck. They are there to earn some cash to get the newest PS2 game or earn money for the movies.
9) Most customers are idiots and don't know that the HDD is not the RAM of a computer. I might deal with a enthusiast about once a week in my store. Over time, you just learn how to sell to idiots.
10) Most will sell you the most expensive product when the cheapest thing will do the same thing. They think more money must mean better. I had an employee try to sell someone Photoshop CS to a customer because the customer wanted to backup their photos onto CD's. I almost cussed him out for that. He didn't even know Photoshop doesn't burn CD's.
Again, most people who know computers work retail till they can find something better. I'm still there because of job security mostly. Hard to quit a steady paycheck when you are on your own. So, before you ask about Ati's R600 at your local Best Buy or wherever, keep in mind: You probably already know more then they do and you should just forget asking.
