Strangest Windows 7 promotion

Today you'll be reading a lot about Windows 7. But i bet you won't see a weirder promotion than this one:

Each pattie is 13cm in diameter and weighs 113g. The first 30 Windows 7 burgers will sell for ¥777 ($8.50), after which the price rises to ¥1450 ($15).

My advice - limit your intake of these if you want to be around to see Windows 8.
