Are you saying that all Mac Pros are manufactured at this factory, but because the number of Mac Pros sold is less than other models, because they're sold to a certain target market, and (possibly) because they're made in the USA they're more expensive then other Macs like the iMac?
Or are you saying that some Mac Pros are manufactured in China, and these are cheaper than Mac Pros which are manufactured in the USA and then sold to a certain target market? In this case, are you saying that only certain configurations of the computer are manufactured in the USA? Or are you saying that Apple somehow manages to get certain higher-end customers to buy the same product at a premium price?
These days, I don't believe anything is true, no matter how reasonable. These days, anything could be true, no matter how unreasonable. So, thanks for clarifying.
