This is certainly not something Microsoft needs to have happen, but it is what it is. Samsung announced it has canceled plans for all Windows RT tablets in the United States, even after it previously announced the ATIV Tab. Samsung USA's senior vice president of Consumer IT Product Marketing, Mike Abary, revealed the company's retail partners showed a modest demand for Windows RT. He also said it'd take too much time and money to tell customers the benefits of Windows RT, so now there's no need. Samsung's decision could end up hurting Microsoft's plans for the tablet world, which is something it's seeked to increase after the popularity of Google and Apple devices. Windows RT already lost HP when the Microsoft Surface was unveiled, and now with the loss of Samsung, things are that much tougher.
