Sadly enough, SpyMac has been the most accurate of any of the rumor sites with everything except the iWalk (which was VERY well done, you have to admit, but it got them the attention they needed and now they are doing honest reporting) and they have FAR more images of Jaguar than anyone else. They are getting a LOT of great new stuff from Jaguar that no one else has. Specifically, the new System Prefs sports a "Digital Hub" section, with Images, Movies, Photography, and Music categories, among other things. No one else reported this.
I have to say, the iWalk wasn't a great way to get started (or maybe it was) but they are giving us a hell of a lot of new things that no one else has... it's really nice to see that. Also, people are NOT saying things like "well, I have the Dev Preview of Jaguar and it doesn't have those features"-- they are AGREEING with spymac on nearly every count.
I think we can trust them now... come on...
