So I'm an idiot. I pre-ordered Office 2011 from Amazon before I ordered my MBA and totally forgot that the Air doesn't have a CD drive. I received the disc in the mail today and my computer is scheduled to arrive Tuesday. Is there any way for me to install Office without the Superdrive (I didn't buy one) or do I have to return it to Amazon and download it online? Is there any type of workaround using Dropbox or a thumb drive? Thanks.
