If you don't think the improvements in the remastered version are worth it, then don't buy it. It would be nice if people who bought the CD/DVD version in the last month or so could get a free downloadable version, but I can see where the extra administration this would require could be too much of a hassle.
If DD had been on the top ten PC games sales every month since it was released, and Larian was making a billion dollars a month from an MMO, then I'm sure they could afford the resources, money and bandwidth to offer lots of free updates and extras.
