This is certainly one Microsoft's better adverts. But the problem I have with it is that IE9 is not on sale! They should have adverts like this for things that people buy rather than things that they get for free as part of a different product (Windows).

The last Windows' adverts I saw were some builders coming into some grandma's house and "turning her home into a laptop store". It didn't mention any features of Windows, and barely featured the product at all.
