This touches on the issue of why companies have amassed such huge reserves and seem unwilling or unable to spend them. Clayton Christensen (of Innovators Dilemma fame) gave an interesting talk at the RSA last month[1] where he described a possible reason for this. Unfortunately only the audio is up but they do often have video so perhaps that'll be there soon as the slides were very important.

The high-level summary is that in order for companies to develop market-creating changes, they need to be willing to make long-term investments with high probabilities of failure. This hasn't happened because the incentives of the management of the company are to provide short-term results which means they choose to only deliver incremental improvements or cost-savings as it has a greater improvement in the short-term on share prices and their remuneration.

He went into far more detail - listen if this sounds interesting to you.
