Except unlike IBM or MS, Apple has never held a monopoly on anything. Its funny how people on Slashdot will both be quick to point out how the iPhone's market share is smaller than other smartphones yet at the same time will try to also claim that Apple is a monopoly. You can't have it both ways.
Still probably isn't a terrible move for Sony even if it doesn't sell too well, as I suspect that they are moving toward convergence with cell phones and that this is a mere incremental improvement.
