According to what I have been able to research, Kodak Gold are primarily good for archiving of data. Apparently, the dye or materials in these survive LONG periods of time much better than other types of dyes or materials, particularly under harsh conditions. So these CDs are not for those of you wanting to burn audio CDs or zip off a copy of unreal tournament. I have been scanning and archiving family photos to pass on to my kids when the time is right-- and that's what I'm using them for. I want to make sure that 10 years down the road when I am ready to re-archive them on the medium that comes next (DVDR, probably, or whatever the hell) my pictures will be safe and readable.
If you don't have critical data like family photos or other sorts of stuff that has to be archived safely for long periods of time, these are probably not the best deal for you.
just my $0.02, based on some research I did a while ago
