+1 to all of the above, go ahead and activate your download. I'm like you in that I always purchase a physical disc, but truth be told, I never even unpack them anymore once the disc has arrived per mail. The dowload itself suffices, maybe just maybe one day that physical copy might just might come in handy... you never know, but it never happened ... sofar.
I even have come to the point where I purchased some games via Steam, no physical copies there! So when, if ever, Steam goes belly up, all those games won't be accessible for me anymore... sooo I buy only games on Steam that I could very well live without.
