I'm still trying to decide which second body to buy as a backup to the D70 and for my wife to use. I've now ruled out the D50, and I'm trying to decide if the D70s is worth $150 more than a D70. My research suggests that the "s" has slightly faster focusing (but did the firmware upgrade to my D70 bring it up to speed?), bigger LCD, and ...? Is there more? Maybe I've missed something on this forum. Thanks for your help.
