Premise: This restraint may partly reflect Microsoft's market strategy--after all, Microsoft beat Apple partly because Apple did practice vertical foreclosure, and as a result inhibited the development of complementary software (although the main problem was Apple's persistent belief, despite all the evidence to the contrary, that everyone would be willing to pay a premium price for a niftier machine).

Hypothesis: Apple prices were 15 percent higher than Microsoft's prices.
Relation: neutral
