Just to clarify, I believe this statement is incorrect. As far as I recall, the 757 is controlled by activation. Therefore, while you can sell the product, he does not have to clear the activation slot for your newfound owner to actually be able to USE the product. This is where DRM does in fact come into play. So, again, if Nicolas already said no, and you decide to sell, it doesn't mean Nicolas will comply with your sale and request for him to free up the activation slot for use on a new machine. I know this may be a waste of a post at this point (since you have decided to no longer sell), but I wanted to clarify this point. It appears to me you didn't think about this part of the whole ordeal.
