On the 'things don't last as long as they used to' front:
I'm really into mechanical and older cameras. They last forever, most of them don't need batteries.
Having those types of cameras also mean having contacts with people who keep these cameras going. I talk to a very old Japanese man in Georgia about my Yashica; older people going into nursing homes have sent me their cameras so I can keep using them.
I really enjoy this aspect of mechanical cameras. If it doesn't work, open it up.
