The mere fact that you opened this post and responded to it tells me your concerned enough to take the 30 seconds out of your life which it entails.  If the article was just nonsense I would assume that wouldn't be the case.

Maybe some one should clue him in on this...

Phase-detection autofocus (even using still targets and center-point only) wasn’t nearly as accurate as contrast detection.

If you want the most accurate focusing you need CDAF.  Even manual focusing is not better...

The contrast-detection autofocus was about as accurate as the most careful manual focusing.

As long as you have time for CDAF it's great. Unfortunately it's far too slow...

That of course is an Urban Legend.

DPR for years (since the GH2) has been reporting that many CDAF cameras are some of the fastest focusing cameras on the market.

(example: "Single AF acquisition is impressively fast - using most Micro Four Thirds lenses will result in some of the fastest focus on any system.")

So while focus tracking is still an Achilles heal, CDAF does offer more accurate focusing and  "some of the fastest focus on any system".
