The services Apple kills are usually rubbish. Ping, Mobile Me, those iPod speakers. Google is killing things that are actually good. I think that is where the Reader backlash came from. Reader was good even if the relative popularity was low.

Hardware is kind of a different thing. The iPod was pretty nice. But now I want a shinier iPod with more features. Production of the Classic just has to match demand from those with niche uses for it. So a slow death makes sense?

Not sure what the situation is with the MacPro...
