Re: iPhone revenue fell for a second consecutive quarter (perhaps due to Apple's failed R&D efforts)

The adult question is whether those facts are related to Apple's
well-documented atrociously low (by percentage of revenue) lack of
R&D.
 
I think they are.

 
No, you brainless troll, it's due to the fact that most people are
simply waiting for the next models to be released, probably next month.
 
Every business in the world sells less in the months leading up to a
replacement model being released, unless they dramatically drop the
price of the out-going model.
