good point with regard to more complex systems. different for mere on/off functionality replaced by standby. NVRAM and EEPROM are cheap and fast. saving settings shouldn't be such a big whoop. and there are more energy efficient ways to do that. a simple AA rechargeable. or you could even go one step further and store settings in the remote which has a battery anyway. plus if you take into the equation the additional production footprint for the standby function even a standby that makes sense otherwise may become totally pointless. meaning if the energy saved by using standby instead of just letting the system run is less over the lifetime of the device than the energy spent to add the standby function... -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
