Quite symbolic. "Hey Nokia - with Elop, you're in our pocket". How's it fell in there?
I think you're reading a bit much into the symbolism there. I mean, if he didn't put it in his pocket, one could have just as well said "Hey Nokia, how does it feel being left out in the cold?"
I read it more like "after playing with all the phones on offer, I'm keeping the Nokia to take home with me"
