To me, nothing... But it's been a running exchange in the thread about some people preferring or think they appear either less or more contemporary than the square and rectangular pieces. I just mentioned that since there's an audience for that. Personally I don't have a preference on the aesthetics of the shape, I just appreciate that airlines overall tend to use more efficient shapes (in this case rectangles) for uses with tighter galleys, like narrbowbody flights.
