If I have to use my hands to pull my phone out of my pocket/bag/whatever, and the easiest way to make the screen point at my face is by holding it in my hand, what do the radar gestures add? It's either a gimmick or they have some very clever new UI features that might be a big change from what we're used to. I'm really hoping it's the latter.
