The standardization of iOS devices is what makes them so easy to use and develop for. Microsoft has done a good job of making Windows behave in a standard manner on diverse hardware configurations on desktops and laptops, so we can hope that WM8 will be equally standardized across different hardware. That would at least give them an advantage over android, and if they don't drop hardware support at certain versions they might be able to take over slowly when the cost of WM8 tablets drop below the cost of an iPad.
