Technological change made Kodak obsolete - there's not much management could do about that. But what really annoys me is how badly Kodak management handled it.

Rather than simply winding down the business and paying cash to shareholders, they ploughed money into developing digital printers and digital cameras; a market with thin margins and where they had very little competitive advantage. It's almost like management couldn't bear the thought of going out of business so they ended up doing something worse - losing more money and THEN going out of business.

I think Microsoft has made a similar mistake. Rather than sitting on it's little nest-egg of Windows and Office and miking the cash until it runs dry, it feels compelled to waste money in areas with no competitive advantage. Bing, Windows Mobile and XBox have all provided a worse return on investment than US treasury bills.
