Why do they have to yell out the words?? It would be so much better if it was just the text and background music...
I'm very surprised people don't like these ads. I think they are well done and a fresh approach. The crowd-yelling effect communicates that using iOS devices is a collaborative, interactive, sharing experience.
And they get your attention, don't they? Mind you, I've only watched them on-demand on a computer, not as part of a series of TV commercials (I don't watch regular TV), so maybe that's the difference.
