They show the Samsung 'bumping' with another. iPhone has done it for years.
They show the Samsung turning on a TV. iPhone can do all that. Mine can work my Entire house Home Automation, my Onkyo Amp, my Sony Blueray, my Apple TV and also works (albiet not well) with my Samsung TV
They show the Samsung being answered with a gesture (several times). My Samsung TV does that too. But hardly ever, and when I pick up a coffee, the volume goes up. Gestures are very much still 'in beta'
Finally, you can take a photo with it with over-saturated colours. I wish the iPhone could do that...
Did they show it hit the ground? No, because it won't last as well as the iPhone. The build quality of the SGS4 is well below par.
But credit where credit's due. They put hot chicks in a pool, so they'll definitely sell phones.
Very average add Samsung. No class whatsoever.
