Dell Computer Corp, the world's largest personal-computer maker, is keenly aware of everything its rival PC manufacturers decide to do. Explain why dell usually reacts more quickly and more substantially to pricing, product design and advertising decisions made by Hewlette packard and Gateway than when these same types of decisions are made by Apple Computer.
Dell, HP, and Gateway largely build PCs which run on Microsoft, while Apple has its own operating system. So, HP and Gateway PCs are much closer substitutes for Dell PCs
