While I agree that OEMs may rebel against Microsoft ultimately the Market will make the decisions on products. As Android and iOS seep deeper into corporate infrastructure RT looses ground and ultimately the product that appeals to the most buyers will be the success story not necessarily who makes the hardware. If the market still demands RT then OEMs will have to step up to the plate in order to hold their share of the market so that MS doesn't walk away with it. That will mean cutting costs to compensate for the difference in the licensing cost and if MS is smart (which I believe them to be given their global success to date) the license will be an internal business unit cost between divisions so it won't be entirely free against the cost of the tablet's bill of material. We can all guess on what the Market will do but in the end whoever guesses best will win the day.
