I hate most of these so-called tech stores. The staff usually know little to nothing. I feel sorry for those who don't know anything about tech and rely on those knuckleheads to advise them. Once in a great while you'll run across someone who knows a little something but that is rare. I think once at CompUSA we ran into a guy who really knew stuff about Macs but I think he was there for some kind of in-store promotion.
Fry's is the worst. They stock anything and everything but you can never get customer service, returns take forever, the shelves are always a mess, and you never know when you're getting a brand new item or one that has been returned and repackaged.
