My first guess would be the seals. While watching that special posted here about Vista at one point they showed a window installer applying a gooey tar/silicone (?) like substance to the edge of the concrete before pushing in the window unit. How long could that possibly last?
Granted, I have no friggin clue. Just a hunch that stuff like that would dry out or crack or fail in someway at least by year 30.
