I want to know the answer to the following question:
Along with the PS Slim's value, quietness, and lower power usage, what superficial quality did PC World praise?
All the background I'm provided with is that "The PlayStation 3 Slim received extremely positive reviews as well as a boost in sales; less than 24 hours after its announcement, PS3 Slim took the number-one bestseller spot on Amazon.com in the video games section for fifteen consecutive days.". Is that enough to answer the question?
