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 Research has a thing called the Sense Cam that, as you walk around, it's taking photos all the time. And the software will filter and find the ones that are interesting without having to think, 'Let's get out the camera and get that shot.' You just have that, and software helps you pick what you want.

There are people who don't like capitalism, and people who don't like PCs. But there's no-one who likes the PC who doesn't like Microsoft.

I'm never fully satisfied with any Microsoft product.

I am saddened, not by Microsoft's success - I have no problem with their success. They've earned their success, for the most part. I have a problem with the fact that they just make really third-rate products.

In this business, by the time you realize you're in trouble, it's too late to save yourself. Unless you're running scared all the time, you're gone.
