If you haven’t already, check out Steve Jobs WWDC 2004 Keynote Webcast. In addition to a new 30″ Cinema Display, Jobs introduces the following new Tiger features:

• A Longhorn-like search mechanism called Spotlight
• A new video codec called H.264 that can stream high-definition video at today’s standard data rate
• Core Image and Core Video
• A visual AppleScripter called Automator
• Safari RSS which provides great RSS support and a new “Private Browsing” feature that keeps everything you visit out of your cache…you know, so you can shop for bithday presents online and your family won’t be able to see where you’ve been

One thing I found interesting about the search mechanism was that they had programmed in things like “wallpaper” to help former Windows users find where to change their “desktop”. It would be very useful if they could team up with Google and use Latent Semantic Indexing to find relevant, but not necessarily matching, content on your machine.
