Apple will soon face tough competition from Google when it comes to cellphone apps, argues ABI Research analyst Bhavya Khanna. Total industry app downloads are expected to grow to 5 billion in 2014, as compared to the 2.3 billion estimated for 2009. Apple will likely remain on top of the industry, says Khanna, but the company is forecast to lose some of its 2010 share to apps from Google's Android platform.
