I am walking with Streak in my pocket and I find it even more comfortable than carrying N900 in the same pocket, regarding its thickness.

As for the "I would like a dork answering the call with it" superstition.
I was playing Dungeon Hunter waiting for a train and my wife called. When we finished talking, a guy standing by asked me "How do you answer calls with your playstation". He was really amazed when I explained it's not a PSP and he asked for pricing availability etc.
