Bill Gates has something to say about the ads in this interview:

In one part of the interview, he states the argument that is being bandied about that Vista is just mimicing features already found in Mac's OSX is not valid, when you consider that Windows came up with the idea of the "file, edit, view, help" menu features in an operating system. In other words, they are the true innovators.
In my opinion, the very fact that Windows took so long to implement many of the visual features in Vista just to catch up to what OSX has already had for a while is unacceptable. Microsoft holds an almost immeasurable majority of the PC market share, and is one of the biggest companies anywhere. They have absolutely no excuse
not to be the leader in EVERY ASPECT of Personal Computing innovation. They certainly have the customer base and resources to accomplish whatever they want.
