I dont think that there really are "killer apps" anymore. These days it seems to be more about a "killer device" like the Iphone or a "killer service" Like Twitter/facebook.
I agree. You need a killer concept. Something that is unique and hard to copy correctly. That's exactly what Apple did with the iPhone. It's a killer combo of hardware, software and App Store service that just works. No ICT product since the Amiga has put a smile on my face like my iPhone does.
Porting any existing application or copying anything else won't set ...(fill in any Amiga flavour your like here...) apart from the competition, hence will not bring more users to the platform.
