I am really annoyed that Nikon has brought out the sb910 now finally admitting there was a problem with the overheating. They should be offering sb900 owners a substantial discount to buy the sb910. I have had overheating several times and even last night when I had to take a dance floorshow, my SB900 did it again. I was so annoyed I missed the best shots because I had to stop and start all the time. I love my Nikon cameras but seriously NIkon you have let me down with the SB900.
