Android is not a serious competitor for Apple because it's not making Google money. It has a negligible app presence and a fragmentation problem. iOS is still what guides the industry, it's what people talk about, it's what Android is copying (Android was going to look totally different before the iPhone came out in 2007), and it's where the developers are.
It took an operating system with no price tag and the promise of total control for the carriers to outsell a single phone. That's a big deal. Even then, not one single Android handset outsells the iPhone on its own, and the iPad still has no legitimate competitors.
More importantly, Apple make huge profits on iOS devices. It has the developers, and it gets the press attention. Android makes no money for Google, barely has developers, and is known as the geeky platform for cross-armed OSS evangelists who hate Apple. It's also experiencing a non-trivial rise in malware--two negative articles came out today in major news outlets. Sorry, but Android is not a serious competitor for Apple.
