My N770 is still going. When I got the N810, the N770 went to my Sister... now it's in the hands of my father, but he's going to be getting his N800 in a few days, so it's going to go to my fiancée. That puts my family as having:

Father: N800
Fiancée: N770
Brother-in-Law: N800
Me: N810 (now dead) and N900.

only thing that died was my N810. Everything else is going strong.
