Agree with that, but
As I had mentioned, what is the use of a great piece of hardware without a piece of software that makes it easy for people to use. I don't really have the time to spend on it, but I suspect that with the introduction of a true graphical user interface, things sort of 'took off' in terms of the average user being able to adopt a new computer and applications much easier than the uneducated could with DOS or any other command line type interface which required more than a point and click level of knowledge or experience. That was the meaning in my message - that the concept of Windows changed a whole lot of things regardless of questions about reliability and stability. As far as 'stealing' is concerned I can't comment on that other than to say that everything is for sale and if they happened to either invest in product or people that allowed them to steal the march then I say, well done. That's what business is all about at the end of the day - competitive advantage and differentiation. Also what allows many of us to have a job and the luxury to comment on this nonsense!
