Yeah, basically what I think. But Nokia have always dropped some sort of clanger with their designs (enter the Nokia 7280, N-Guage and the 7600)
If your headphones have got a 90deg jack on them then you either block the stylus or hinder the unlock switch. the socket should have been top-left by the volume/zoom rocker.
As for the charger socket. I think that should have been bottom centre. Would have been a great position for designing desktop cradles.
And the lanyard hole should be where the headphone socket is now.
