The very knowledgeable and friendly salesperson showed me a MacPro. I said, "wow, rock on dudes," and walked out.
I used to sell Macs at an Apple Specialist. If someone walked in with minimum specs that didn't match any configuration, I'd direct them to the nearest box-pc store. I'd also ask them what they wanted their computer to do. If their needs were so minimal and the cheapest Mac Mini was outside their price range, I'd again refer them to the cheap pc store. If they were open to spending more to get a Mac that would fulfill their needs, great - I'd spend time with them. If they, however, were absolutely fixed on price as their primary parameter, I'd apologize that we had nothing for them and direct them to a cheap-pc-vendor.
There are consumers out there who can only be satisfied by "price". These aren't consumers who can be "convinced" that a Mac should be their next purchase. They haven't reached that point where they can be convinced to "switch". Until they've reached a point of frustration with Windows that they're considering spending more than their "ideal" price for a computer system to get something that works, they'll remain bargain-basement-pc-people, and only a cheaper price will satisfy them.
