One other thing:
“Figures released in the US claim Apple controls almost a quarter, in fact 24% of the smartphone market. ”
Another way to put this is that 76% of the market is up for grabs among the other manufacturers. There are plenty of Apple haters out there, or people who are simple fans of the Android, Windows 7, or WebOS platforms.
I’d expect the companies that do launch new devices to take market share away from those who don’t.
