I've definitely seen it...I still don't see the point, so one person is really fast it? I'm sorry I just like to be able to walk/sit around and text without looking at my phone, seems alot easier then having to concentrate on what I'm swyping my finger over while texting.
edit: I took out my old LG enV touch and typed that commercial out about 6 secs slower then he did the first try, sorry I don't have the money samsung does to fly in the guinness book people.
