Yeah, thats what they said to Apple and Google when they introduced their OS to the market. "It's too late because Microsoft owns the market, no way anyone is going to use an Apple or Google OS." Fast forward to 2013, and the OS market looks a whole lot different. Why? First, never underestimate the consumer's demand for more choice. If Android and iOS is dominating the market and then Windows8 and bb10 come out with products that not only perform as well as the market leaders but are just as beautiful in design, then more viable choices will lead to market erosion for the leaders.
