This is probably my first post on Macrumors despite having been a member for awhile, but that I aside I decided to come out of the woodwork because I was really bothered by the tenor of some of the posts in this thread.
The comments regarding the "lousy employees" and "Yippee! Sale!" I think are pretty callous.
Yes, I know in these stores you are unlikely to find superb or knowledgeable sales people, but then that's the consumer's fault. You demand high performance at a low price with an almost open-ended return policy AND you expect every employee you talk to know the answer to your question. Sales people like that do not grow on trees. Furthermore it is not reasonable (nor is it economically feasible) to expect chain stores to hire 50 upper tier, knowledgeable sales staff at their realistic market value. The electronics world thrives on a very low profit margin and depends on volume to stay in business. Someone who is knowledgeable enough to pass your muster probably isn't going to be working at best buy or circuit city for $8/hour. There's an old retailer's adage that goes "Price, Service, Selection. Pick Two." Best Buy and Circuit City are Price and Selection. If you want service you need to find a local shop in your area that hires folks passionate about what they sell. No, you may not get the best price or even the best return policy, but you will get someone who knows what they are talking about. SHOP LOCAL!
Despite all this there most certainly are some quality employees that work for Circuit City and, perhaps more importantly all of the Circuit City employees are people who are losing their jobs.
Peace.
