Are you talking about the keynote or the developer content, the keynote it seems to be the Apple's keynote has much more effort put into how and what is presented - there's also functionally two distinct keynotes, the primary and the State of the Union which is entirely developer focused. My /impression/ has been that the individual developer sessions are much better and more clearly presented. The other aspect - for developers - is Apple has like 40 years of being an actual OS developer, and recognizes that ABI stability matters. Even when APIs are superseded, the old APIs remain for many release cycles - not to MS levels of insanity, but not far off. As a result the APIs are designed for longevity, and considerable thought is given to ensuring that APIs should be sufficiently forward thinking to avoid the need for frequently replacing APIs with new APIs that do the same basic thing. A result of that is the developer sessions have value for more than single OS release - and remain available on the WWDC site for many year.
