I don't think it will happen. For one thing, at least a few of the D900T components were not manufactured with Vista or 64 bit computing in mind, so we would be looking at replacing more than just a motherboard. It just wouldn't make sense for anyone to manufacture a replacement motherboard that is already somewhat functionally obsolete. Also, despite the fact that these companies which sold the D900T know of our dissatisfaction, they also know that we are suckers for the lastest and greatest, and that we'll pay top dollar for it...and give them our business again. Bad for us...great for them.
