theodp writes: Remember New Coke? Twenty-eight years ago, Coca-Cola replaced the secret formula of its flagship brand, only to announce the return of the "classic" formula just 79 days later. Had it launched in 2013, Coke's Jay Moye suspects a social media backlash would have prompted it to reverse itself even sooner. In a timely follow-up, ZDNet's Steven Vaughan-Nichols points out that Microsoft is facing its own New Coke moment with Windows 8. 'Does Ballmer have the guts to admit he made a mistake and give users what they clearly want?' Vaughan-Nichols asks. 'While it's too late for Windows 8, Blue might give us back our Start button and an Aero-like interface. We don't know.'
