The extra headers and the size of the PC board can't add that much to the cost.
I might get shunned for this but one of the major draws to the arduino for me was the removable chip (and the easy language)
but I'm one of those "just because" and "just in case" buyers.
I guess it does come down to the extra headers, PCB size and MCU cost.
