I was considering downloading the evaluation 8.1 and either using the license from my current PC, or just buying a new one so I can continue to use this one until all important documents are off this machine. So my question is can this work? Or do I need to actually have a disc? I didn't get a cd drive for my new PC because I don't really use my old one anyway, and if I do need it I figured I could just take it out of the case. So, what are my options? Do they still make external drives for DVDs etc?
