There is an interesting article on today titled "The Distributor vs. the Innovator", taking as example the current dominance of HP in the printer market and the big threat Dell could become in the coming years as it expands their product reach to corporate and home users.

Dell admits it, they are late for the party but they plan on taking heavy measures in order to become competitive (lower prices, anyone?), in the other hand HP simply says, it won't be that easy.
