Everyone is posting this video because Steve Jobs has a cameo as FDR, cigarette and all. You can tell that he really invested in the role and put a lot of effort into the accent, thus making his performance all that much more hilarious. Here's the clip with Steve's cameo:
Most blogs are posting the video simply because it is hilarious, but I see it a different way. Some time back I posted the classic 1984 Mac commercial with the question: When did Apple go from being the runner in the video to being the evil monolith?
Today's video gives me an even better chance to make that point again, only this time I get to contrast Steve as FDR in 1984 with Steve as Hitler in 2010 (the iPhone 4 leak):
This second video is satire, but it's not all that far off the mark. I'm not sure if you recall the hostility Apple displayed towards Gizmodo, even going so far as to sicking the police on Jason Chen the blogger who wrote the story. But they did.
You might recall Apple's repeat performance last year when another iPhone went missing. They had, I kid you not, SFPD officers escorting Apple's security folks in searching people's homes - while looking for a phone.
What's more, given the behavior commonly attributed to Steve, the Downfall parody gains an extra element of truth. Steve Jobs really did go from the hero to the villain over the course of his time at Apple.
