Hmm, that's interesting. I was about to say that NT wasn't a rewrite but it was a completely different operating system designed from scratch, well I guess a little of the design came from VMS:)

I see your point on how you consider this to be a rewrite.

I guess the question I have is, what's the difference between a brand new product, and a rewrite? Up until now I considered windows NT to be a brand new product.
