Apple demos HTML5, CSS3 and Javascript

Apple's developer site has a collection of 'who-needs-Flash' pages that 'deliver rich experiences'. While these demos are targeted for Apple's Safari browser (under iPhone OS, Mac OS and Windows), it provides a sampling of HTML5, CSS3 & Javascript  that can be viewed (or not) in your favorite browser. Does this change anything for Flash designers/developers out there? Or is this simply another option for crafting a richer user experience?

Here is the breakdown as it looks like right now:

1. Video Effects
2. Web Typography
3. Web Gallery
4. Photo Transitions
5. Audio
6. 360
7. VR
8. Pixel Manipulation
9. Sticky Notes
10. Concert Poster
11. Checkers
12. Light Table
13. Offline Calendar
14. Movie Trailers

UPDATE: Apple has blocked viewing these demos with anything except the Safari browser. Booooooo!
