I have rMBP which doesn't have DVD drive. Here come the questions. 1) If I purchase a physical copy, can I download full image file from web? 2) In the box of a physical copy, how many DVDs consist CS6 Master Collection package? It says I can install CS6 on as many Macs as I want, but I can have only 2 of them activated, and I can run only one of those 2 machines activated simultaneously. 3-1) If I run CS6 on two machines at the same time, will Adobe know and limit my license? I usually leave my desktop turned on having many apps opened, even if I'm out with my laptop. If it's the case, It thinks I should be careful. 3-2) What if one of the machines I have activated is totally wrecked, so I cannot turn it on. Is there a way to deactivate it? It not, do I lose one of two slots of activation? I'm senior at college and graduating this Feb., so this is the last chance to get CS6 student discount version, which is 80% off from regular price. Any answer would be much appreciated. Thanks!
