D800 AF issues: grass is always greener...

While the accuracy at best may be only as good as CDAF that's only half the story as the speed can be significantly faster particularly with tracking focus which CDAF is no good at as it can't tell which direction the focus is unlike a PDAF system. The issues with the D800's AF system are not inherent to PDAF, the D700's PDAF system is not only accurate but far faster than a CDAF system.

As for the topic, I did get a slight chuckle out of having left Olympus and gone to Nikon due to serious AF problems with the E-3 that Olympus never acknowledged or managed to repair despite being a widespread issue.
