Interesting, though I was a bit taken aback that it turned into an ad for Keynote around slide 60. Not that it doesn't have merit, just made me raise an eyebrow.
The whole thing is an ad for Keynotopia, so it's not that surprising. That said, a hugely useful ad, which has me pretty excited about trying Keynote for mocking up an iphone app. I didn't know Keynote could do hyperlinks.
