The people at PlayStation sent me a PSP carrying case and a press release about how great a year it's been for Sony's handheld video game system. That's nice. But was truly special was that the carrying case contained a carboard PSP. It is slim, light and does not consume electricity. I believe it absorbs spills more effectively than a PSP 2000 or even a PSP 3000, but I haven't tested it yet.
See the cardboard PSP right below:
Yes, it looks just like the real thing. What did you expect?
