It was so long ago when Nintendo first announced the DS. How all laughed and jeered. Two screens? What a stupid idea! Well now that stupid idea has been proven not so stupid over 50 million times. Selling a hundred times better than your average hotcake, Nintendo's handheld gamble has paid off big time. In contrast, it took them 11 years to sell 100 million Gameboys, so as PC World points out, the DS should easily surpass that if momentum continues.
