Both ARM and Intel architecture will be Windows 8 compatible and we feel that the backward compatibility of Intel processor with older versions might not suffice as a significant differentiating factor.
Consumers often care about backward compatibility as well, but it is even more important for businesses since they typically have made much bigger investments in related software, documents, documentation, training, and so on.
And as we add the Advanced Wireless Services (AWS) spectrum, 700-MHz spectrum, LTE and UMB to the mix, I expect the Gobi chipset to keep up and provide for these new bands and capabilities, as well as full backward compatibility.
Bug-for-bug compatibility is a problem, but breaking backward compatibility would be a much bigger problem, so even as the lowest layers of the operating system are revised and rewritten, the layers that applictions talk to (the application programming interface, or API) are carefully tested to ensure that no changes are visible to the application.
Rather than talking about backward-compatibility, enterprise now has to embrace forward-compatibility, designing systems based on new technology to meet evolving user needs and creating customer value.
To overcome the problem of backward-compatibility, modern x86 chips such as the Pentium are able to take x86-style instructions from old software and split them up into several smaller micro-operations which lend themselves better to performance-enhancing trickery.
