Despite the reported failure of the PS3, Sony continues to push PS2 units at an impressive rate.
That's why Sony went to work on cutting down the cost and weight of PS2 production to make them even more profitable. The new PS2 is a whopping one-third the weight of the old PS2. The console has been trimmed from 900 grams to 600 grams and the power adapter has been slashed from 350 grams to just 250 grams.
While the external frame remains unchanged, the lighter console makes for easier portability and awesomeness.
