What has Adobe worked out with Facebook. All pre-intel chip Mac G4s, laptops, towers, et and OS 10.5 will not allow Flash content to play on Facebook, while watching on Youtube or other sites streaming the content work fine using the Flash player 10. This doesn't add up. Meaning all pre-intel chip Apples, OS 10.5 or before, are expected to enjoy a limited edition of FB - less any flash content, while all streams fine from Youtube. What a cram down!
