CDAF systems are measuring focus at the sensor. Generally when they get a lock its dead on (within the DOF limit anyway) provided you shoot an object with enough contrast. Yes, they can be fooled, but not that often. Moreover, manual focus check on the EVF is always accurate (not always true for SLRs).

This simply is not true. I have 2 years experience with my X100 (and more with my S200EXR) and it is not a rare event when it "locks on" but ends up completely missing focus.  It's become almost a given here that CDF is somehow more accurate than PD but I cannot agree with that because my SLR's slaughter my X100 and previous contrast detect focus cameras in ever possible way.

SLRs are not really very good at AF. D7000's, 5Dmk2s and many other cameras had AF that I would class as barely adequate. My D700 would back focus under tungsten (as do most SLRs) and on some fast lenses would focus shift noticeably. Perhaps your just never noticed?

SLR's are the bench mark of auto focusing.   There is no way around that.  If Fuji's cameras focused as good as an SLR, these discussions would NOT be happening.
