Regarding Android vs. iPhone market share
According to NPD, more smartphones were sold in the US that run Android than smartphones than run iPhone OS in Q1 2010. BlackBerry remains in the number one spot. According to NPD. Apple isn't a fan of the metrics being used:
“This is a very limited report on 150,000 US consumers responding to an online survey and does not account for the more than 85 million iPhone and iPod touch customers worldwide,” Apple spokesperson Natalie Harrison, told The Loop. “IDC figures show that iPhone has 16.1 percent of the smartphone market and growing, far outselling Android on a worldwide basis. We had a record quarter with iPhone sales growing by 131 percent and with our new iPhone OS 4.0 software coming this summer, we see no signs of the competition catching up anytime soon.”
Since Android can be found in a variety of form factors on all four US carriers, and since Verizon offers it as part of their BOGO (buy one, get one free) promotions, just like the BlackBerry, even if the NPD numbers hold up they're not surprising.
That the iPhone's market share is so high in the US, given they're on one carrier with one form factor, is actually more surprising -- only that it happens so often now we've stopped being surprised, especially after Apple's last financial results statement.
And yes, we're tired of beating that old horse as much as you're tired of watching it get beaten, but Apple cares only about market share as much as it amplifies profit share. Google isn't making direct money off of Android (though they do off monetizing services like search, which they also monetize on the iPhone) and on the low-margin, BOGO devices that give BlackBerry its lead, they're not making Apple-sized margins either (they likely do better on Bold-class devices).
Needless to say, Apple's not letting AT&T do BOGO for iPhone. For Apple, the iPhone is a premium product and they'd much rather maintain their huge lead in profit share than line discount bins for the sake of market share.
