Having watched the event Live on YouTube on it's announcement, have to say phone aside, they probably prepared for months for that presentation. I have never seen such a presentation for company when they are launching new product. It was more or less Play or Drama
Anyways have been following S4 days before it's announcement, have to say it's undoubtedly the best phone available on market. Samsung has really stepped up with all their new innovations and are now easily way ahead of competitors. Only thing that bothers me is it's design but I am not the guy who go for looks. Watch it's live demo of features, not a video which doesn't show a thing.
Looks very good, but expensive.
It's still 100$ less than overpriced and outdated iPhone 5.
