Do i buy through the app store or spend a little extra for a used box copy of Studio? That is the question. The box seems like the best choice given that it's price is reasonable, but i have some difficulty deciding. I've found a used box that goes for about $100 over the app store. I know the box has a lot of extra content, but what practical differences is there besides that? Can i use the boxed copy on multiple machines for instance? From what i hear that is the case with the app store purchases. Can there be any licence/serialnumber issues with the old user if he is "sneaky" and continues to use the software? What does the in app purchases cost within the app store version? Is it sold in packs or plug ins separately? How much would the $100 i would save get me in extra content?
