I agree. Jesus needed to be seen as having truly conquered 'the trials and temptations' that man was daily confronted with. To do this, he needed to be as man was. to live as man lived. Otherwise his victory over sin, would have held little significance, were it to have been done as a GOD. It would have been more like he had "cheated".

Overall, his human nature put him at par with man, so that in his victory, would man found the faith, and the strength to overcome sin. If Jesus could overcome sin, Who are we not to? He was after all a man.
