First off, sweet buddy icon Neospawn.
Secondly, the pictures the link goes to are a bad representation if you ask me. in those it looks like he has controls to either side of his knees. In the movie however, his hands were strapped to the APU's arms, and it seemed to me that he was having to flex his arm to move the arm of the suit. Also in the picture it looks like he is sitting, in the movie (If I remember correctly) his legs were straight, and 'attached' to the APU's legs. But to tell you the truth I was so busy watching how cool that scene was I wasn't really thinking "I wonder if that's a hardsuit" :)
