Agreed Fur. I prefer the digital download.

Nothing like rushing home with your multiple copies of a new release only to find out your are missing the cdkeys in a few of them. Digital upgrade has been immune to this when I have used it. When I upgraded to a full 5 accounts I got my battlechests at Best Buy. When I opened them up I was missing the vanilla wow cdkey but the bc keys were there. I did get them exchanged but it was still a hassle having to drive back to the store. There was also a bunch of pilfered cd keys from the bc only boxes. The CSR forums were full of posts about it.
