This is a bit interesting. The flash movie intro for the Sony Playstation 3 site has one frame of Apple's logo, flashed only for a second like those Simpsons in-jokes. What does this mean? Well, remember when Soy said their chip can run OS X? Maybe this is their way of telling everyone they're still on that?
More likely, it's some web designer just throwing in a shout-out to Apple thinking only a few people would notice. Well a few people did, and they sent it to Kotaku!
