The original magsafe design ( http://www.iclarified.com/images/news/9014/31392/31392-500.j... ) was the most ideal desing out of all of them in my opinion... I have seen macbooks slide about 20-30cm with the new designs without the magsafe connector disengaging, all because the of direction of pull.
The only problem was that the original magsafe design was prone to fraying. and probably didn't look as sexy as having the cord at a right angle to the computer.
