Microsoft doesn't charge for this type of material now-a-days and I was expecting the same from Apple. Big conferences like the PDC2008 are free^^. And of course there are plenty of free conference materials in other domains (Java, python and ruby).
So what's up with Apple being evil recently? It's been my opinion that one of the few things Microsoft does right is keeping it's developers happy. I would think this would be common sense to a company like Apple.
Has anyone spent 500-1000 to buy the WWDC sessions and was it worth it? Is it that different from material like PDC2008 that it's worth 500-1000 bucks?
