It would be nice if they just put both in the box. At least, if they are going to put X number of cd's in there anyway. I definitely prefer to just put in one disk, run the installer, put everything on my hd, then archive the original disk somewhere away from greasy fingers, sunlight etc...
Oh, and I do have a couple of DVD drives. Damn region coding of movies makes it easier to have a drive for each of your favourite regions (1,2 & 4 in my case ))
