And that is the contention point.Verizon seems to be doing just fine without [the iPhone]...
Some analysts believe the opposite is true (see above CIO link).
I believe there are two different questions that get (intentionally or not) switched around in discussions: revenue/profits and market share.
Apple's iPhone does very well in the former and not so good in the later. The reverse is true for Android.
One can make a point that a steady loss of market share sooner or later affects revenue. Case in point: Nokia.
But the smartphone market is growing at such a pace, this correlation won't work for a while.
