I really am getting frustrated with those of you whose answer to all the dongle problems is simple buy new cables. After buying one of these computer I would have no money for food never mind new expensive cables.
If that is the case, you shouldn't buy the computer to begin with, you cannot afford it.
Everyone is screaming about this being a pro machine and at the same time screaming about having to use dongles and the price of cables. I haven't worked for a company yet that even blinks at me saying I want a second $3000 machine, they just get it because they want to make money. They will not bitch about a $30 cable.
