Cheap(er) almost always beats better/best when the market is large. Walmart, fast food, webbrowsers. The main way a less cheap product wins a mass market is through massive advertising. Specialized and niche markets are different. I'm not sure what your examples where suppose to illustrate. Both Windows and Adsence rule because of the (practical) monopoly positions of their creators. iPod's only one that may have dominated for being the better product but If google started giving away crappy media players they would quickly out dominate iPods.
