Killer app = software that sells a significant amount of hardware

Evergreen = software that sells a long time

These are the simple definitions I use.  What definitions do you use?  These two words do not mean the same thing even though their is a correlation between them. 

The very post you quoted already answered that question, though I suppose I should've added that the best killer app a system can have is no singular game alone but a vast and diverse library with many different games to suit the many different tastes of gamers.
