If anyone is looking to this thread to give out keys, I would appreciate one as well. Played SC/BW religiously for four years and have been comping at the bit to try out SCII.
SC: BW copies are as small as 80MB now if you dl the non-cinematic copies from Blizzard's Store making it a perfect game to play while at university. Have a slow lecturing professor in a lab? Access to a computer with a 1MB/sec downloading speed or greater? Play starcraft BW in under 60s! Great lan game too and if you can vince others to play with you. Why not? Its only their grades your sabotaging with an unending addiction.
Getting a key on Facebook is basically impossible. I tried all last week, and you have to be able to read and type a key (which is sometimes written in mirrored form) in well under 5 seconds. My best so far is 7 seconds while my brother read the key out to me...still didn't get in.
