Why is Nokia trying to sell at low price points?

I have been whining about this over and over, in a bunch of my recent comments on various websites.

This latest article also adds to it.

But, I think there is one point where one can stop worrying.

This:

Nokia 'makes/plans to make' money from WP and Win8 ecosystem via Location and content services. Even if HTC sells an 8X, Nokia is probably getting $$ and so, they don't care to cut margins on hardware.

I don't see any other rationale in this rush to make smartphones so affordable. What say?
