Reply to Why are people still using cdj's with timecode?

Hey. I really hope this thread doesn't go down like the sync/tt vs controllers one...

So, i was just watching dillon francis' perfomance at holy ship, and he was using 2000's (don't know if nexus, they're pretty much undistinguishable).
Now, apart from the great performance, i was curious about why , in jan 2013, was he using DVS (ssl) with a pair of capable players such as the 2000s.
Now many may bash me here, "he uses what he wants to, he's dillon francis and who are you to criticize him in the first place"; i'm not hating on anyone, of course he can use whatever he wants to, but i just have a pair of questions that maybe you could help me find the answers to, no hate

So, bear with me:
Cdj 2000s are a standalone platform with waveform displays, hot cues, loops, integrated effects, bpm detection, basically everything a dj needs. So why would someone use a system that was designed for turntables, that cripples some of the functions of the players themselves, but doesn't actually add anything to the setup except latency? What functions does SSL have that a standard cdj2000+djm900 setup doesn't?

I mean, even with the "old" 2000s there is rekordbox to manage songs on a computer.

I know MANY of you will not agree with me, but i feel like using DVS on an already digital system is like trying to get from A to B while building a wall in between the two points.
