I think most would be as frustrated as the OP but not sure how cancelling the order gets him a system any faster. Apple is the only place where he can customize the system to his exact specifications so it's not as if he can go elsewhere. If he is able to work with one of the standard configurations an alternative retailer has (say B&H Photo) then maybe he can get what he needs there. But ultimately he's stuck between a rock and a hard place.To the folks who think it's an over reaction, I guarantee you all would be singing a different tune if you went through the same scenario. The OP seems to not be satisfied with the service and he doesn't want to be a patron of Apple due to that. That is his prerogative, period. But I'm sure you will continue to go ahead and give him more advice on how he should spend his own money lol
IMO the OP was a little hasty and all that will do is delay his eventual receipt of the system. I assume the OP order the system because he feels it has value to his workflow and, if so, he will buy one. Maybe he'll wait a month or two and re-order. But then he will have merely delayed his purchase by a month or two.
I've gone through something like this myself, I suspect many of us have and can relate. But I feel the OP is cutting off his nose to spite his face.
