For less than 2 of these you could buy an Allen and Heath 4D which is way better for digital djing than these will ever be. (Controller and mixer!)
If they want to design for digital dj's, lose the cd player and design something that is portable!
I'm not convinced it's the right step to be honest..
Looks cool, but not really what I'd look for from a purely digital Dj perspective.
Far better options out there!
They are trying to give people a software DJ experience with hardware. But the problem is that any DJ that invests in these would have to be certain that clubs will have them too, so he can just turn up with his memory stick and play. These have in-built midi support for Traktor and Serato though, so that's pretty good. DJs can still bring their laptops. But in a way that seems to defeat the purpose of all the features these CDJ2000s have built in. They may have left it a little late. So many DJs have already moved to laptop & midi-controller.
