Out of curiosity, why does a phone deserve a better camera than a media player?
What an interesting question! Did anybody actually argue that a phone deserves a better camera than a media player? I looked through the thread and didn't find anyone saying that, not even the person you quoted. They said if you want a product with a particular feature, then you should buy that product! It's too bad Apple doesn't do exactly what some people want; that doesn't mean they've done anything wrong.
On the other hand, there have been plenty of threads saying that the iPod Touch 'deserves' the same camera as the iPhone. Maybe it's that sense of entitlement you are thinking of.
