When GOG first appeared I was against it, because it didn't feel fair to sell something that is free (at AB) and nicely working like Cannon Fodder for instance.
But then they started giving some stuff for free and when I checked their site I kind of understood what it was all about from the good point of view.
I still didn't buy anything there and probably won't in near future, but it was nice to replace my old pirated copy (that was bought when there were no way to buy legitimate games in my country) of Empire Earth with legitimate one (which is of course improved with expansion and bonus content).
Like EoF, I too like hard copies but there are numerous advantages of digital download, GOG tought me that if nothing else. But I still had to burn EE to CD and put it in old box, so that the replacement could be complete.

Abandonware titles aside, GOG is selling Seven Kingdoms AA, and that is a freeware title, so that is not very nice of them.
