Here's the video, from the Lumia channel:
It's an effective video that strikes just the right line - showcasing benefits without gimmicky dance music and renders. You're left thinking 'I can picture myself doing all that'.
The only wrong note in the whole presentation is when the man flips the phone to reply an email with Wordflow in landscape mode - being based on swipes, Wordflow is much, much more effective in portrait mode, using just the thumb. The only time you'd use the landscape keyboard would be if you wanted to type in the traditional fashion.
Still, that's just me being picky. The message of the video is clear, production is top quality and there's an inspirational finish. Well done all.
