Why not? Am I wrong?
What was the PS2's killer app? X-Box 360? Nintendo DS? PS4? PS3?
If you're saying "what has this world come to", it implies that past systems have always, or at least usually, had killer apps available at launch.
So, how are you defining killer app, and what have those killer apps been for past systems? If you can't come up with a decent answer to that, then the comment kind of seems trolly.
