Lol its not about coolness crywolf, i think controllers are cool, but are honestly more toy like than a professional solution, most i tried it was very hard to beatmatch manually with little jogs and touchy, small pitch faders. Plus you are taking all this gear when you can rock up with cds, usb and headphones if you use in house decks, plus you can blame the club when the gear fucks up lol. Producers i dont mind as they use up so much effort and time producing their songs, so i can understand them running out of time or effort for full in djing. Plus im sure lots of them dont want to dj but demand from clubs and fans makes them.
