Microsoft exec Steven Sinofsky described the claims as “factually inaccurate and unfortunately misleading.” He noted that Microsoft’s development goals were clear and that the technology was still in its demonstration stage, which is basically a fancy way of saying that it doesn’t really work yet.
However, Sinofsky did not get into specifics and it is still somewhat unclear what Intel got wrong to begin with. An Intel executive claimed that Microsoft would release four Windows 8 SKUs for ARM processors and that legacy apps would not be supported.
So far, Microsoft has not outright denied either of the claims and punters doubt that full legacy compatibility could be possible anyway.
