Gay and stupid, would have to sync tunes onto the ipads, would have latency and quality issues, no tactile control, more than likely alot of issues. All when you could have cdj200s sitting there which would do a better job and would be more suitable for a club so djs can bring their usbs or cds in easily. Grem pretty much covered it. Unless you're using iPads are whatever as a clip launcher for Ableton, I think they're a huge wank. Also, the headphone jack on the DDM is in a horrid position, I know this from experience.
