Thanks to Engadget for sharing this great image of Burger King Japan's limited time offer "Windows 7 Whopper" with a whopping 7 layers of beef. Stupid? Yes. Disgusting? Yes. But apparently, a great idea. I Binged "Windows 7 Whopper" and found that the advertising gimmick is super successful. Everyone's talking about it. How many times did you see it on Facebook?
