Bernstein Research analyst Toni Sacconaghi has forecast that, if its sales figures remain consistent, 50 percent of Apple's profits will be generated by the iPhone in 2011.

In 2009, the iPhone was apparently responsible for 30 percent of Apple's revenue with over 20 million units sold.

This figure is predicted to increase to 50 million in 2011, which, coupled with expected sales figures of over 2 million iPads in 2010, suggests there's no end in sight for Apple's continued dominance of the portable consumer technology arena.

In addition, Steve Jobs announced during the company's recent shareholders meeting that Apple's $25 billion cash reserves won't be used to pay dividends or buy back shares.

This astronomical figure is apparently being held in reserve as insurance against research and development projects, suggesting Cupertino is nowhere near finished with its reinvention of personal computing.
