I think it is just that you may well have had the discussion a 1000x but someone who is new to this forum or indeed, digital art, 3d or whatever, may not know that! If you are fed up with answering the same question, don't answer it. Leave it to someone who is more "helpful" and/or sympathetic to newbies. :) Like you said, if this question comes up, the best way is to explain the difference between the 2 programs and their basic functions. If you have examples of comparison than that is great, if not, just a simple explanation will suffice. I was more upset at the general implication that one is "stupid" or "dumb" to ask such a question. It does us all good to remember what it was like when we first came across new software, media or whatever. It isn't easy and everyone has their own learning pace. Some need help, others thrive by working it all out for themselves but are then very good at helping others!
