Defenders of Apple's monopoly offer hard-to-test claims, but many boil down to the idea that Apple's product is inferior by necessity. This will, in turn, cause developers to skimp on testing for Safari, making it inevitable that browsers based on WebKit and other minority engines cannot compete. Or so the theory goes.
