From the very first time I saw the C1, I couldn't help but think of it as the "retarted's midi keyboard". Seriously, there is absolutely nothing evolutionary about it, besides the MIDI IN port. And it is completely irrelevant anymore, because of Traktor/Serato. And by the way, that MIDI IN option is sported on the PDX3000. At around 1/5 of the price, 4/5 of the size and 3/5 of the weight. Minus those little buttons adding up on the C1 nothing else but overall maintenance cost.
