Meh, is anybody seriously surprised? It would be a mammoth task to fit a central warning computer or whatever Boeing would call it into the 737 to replace the ancient master caution annunciator... If they manage to improve the airflow in the cockpit (I don't need my neck and forehead ventilated, thank you very much), perhaps make it another smidgen quieter and throw in a multiscan radar as standard I'd be happy to go back to the 737
