Hello, A question for those who recently purchased above: Is the included Silverfast Ai 6.6 software compatible with Windows Vista 64 bit? The Silverfast web site was not to helpful on this regard. (I know thier new Silverfast 8 IS compatible, but Epson ships Silverfat 6.6, not 8). I am trying to decide to buy this scanner or not partialy based on the cost, if necessary, to upgtade the boxed Silverfast Ai to a newer 64bit compatible. I shoot 4x5 at times so I am particulRly interested in this EPson. Thanks in advance for any useful info.
