At Microsoft there are lots of brilliant ideas but the image is that they all come from the top - I'm afraid that's not quite right.

The way to be successful in the software world is to come up with breakthrough software, and so whether it's Microsoft Office or Windows, its pushing that forward. New ideas, surprising the marketplace, so good engineering and good business are one in the same.

Microsoft is not about greed. It's about innovation and fairness.

I'm never fully satisfied with any Microsoft product.

In a sense this is the end of an era. Microsoft and the original PC rose to prominence based on the MS-DOS product. And even as Windows came along, Windows 3.1, Windows 95, Windows 98, underneath MS-DOS was running there. Windows simply sat on top of MS-DOS. Well, so today it really is actually the end of the MS-DOS era. It's also, we would say, the end of the Windows 95 era.

Driving up the value of the advertising is a big commitment for Microsoft.
