nope. doesn't use AA. uses special rechargeable niMH (think it might even be a standard camera battery). he's gone through three of them in four years. not bad, considering he's probably taken 5000 photos by now.
i was going to buy a coolpix once, and decided against it due to the aa battery thing. i went canon powershot. kickass. even holds an IBM Microdrive. when i put the microdrive in it, the display says "999 pictures to go" all the time. so much room, it can't even fathom it.
