Input: Article: Technology magazine T3 gave the Super Slim model a positive review, stating the console is almost "nostalgic" in the design similarities to the original "fat" model, "While we don’t know whether it will play PS3 games or Blu-ray discs any differently yet, the look and feel of the new PS3 Slim is an obvious homage to the original PS3, minus the considerable excess weight. Immediately we would be concerned about the durability of the top loading tray that feels like it could be yanked straight out off the console, but ultimately it all feels like Sony's nostalgic way of signing off the current generation console in anticipation for the PS4."

Now answer this question: According to T3, what was the main differentiator between the "fat" PS3 and the Super Slim?

Output:
weight
