"Microsoft's new mantra: 'It Just Works' ripped straight from Apple's 'Switch' campaign" according to MacDailyNews.
MacDailyNews Take: Allchin must be an idiot. He certainly sounds like one. He's been "in charge of Windows for almost a decade." 'Nuff said. Oh, one more thing, where'd he get the phrase, "it just works?" Straight from his number one supplier of ideas, of course, Apple Computer: http://www.apple.com/switch/whyswitch/. Stay out of those Apple "Switch" pages, Jim. We know you want to — and who could blame you, being so frustrated by your current operating system — but it'd probably be a tad detrimental to your job security.
Jim Allchin has been using that phrase for years, I remember it being used back in the '95 days, and it was widely used in Windows ME's marketing campaign. Three years before Apple's switch campaign.
