From the video, it seems that the phone that the FayerWayer guys had was the first time that Woz had played with iOS 7, which makes sense since this happened the day after the WWDC announcement. Woz said that he really liked the design, but admitted that he did see a lot in there that was similar to other platforms. And, he still found some things that weren't as smart as Android, like having to still tap the delete button on a message after swiping instead of simply swiping it away.
But, the majority of the interview has Woz talking about PRISM, and that's the really interesting stuff. Woz talks about the US Constitution, and says that he can't understand how the Patriot Act and laws related to it have come into existence and can be considered constitutional. Great stuff from Woz, definitely worth the watch.
