Call me a "doubting Thomas," but I am still cynical as regards AFCI products. Without regard to what the mfr claims, and considering the economy of GFCI devices, I would prefer to have a GFI receptacle where GFI protection is required.
The AFCI, however, has to be in (or real close) to the panel- which may be nowhere near the receptacle. Leads to a game of "hide and seek."

The code may require AFCI's, and the mfrs may claim wonders for them, but I will only tolerate them until there's some more of a track record for them.

In fairness, my cynicism is partly inspired by the "bait and switch" campaign pulled by the mfrs in getting these things into the NEC. That, however, is another thread.
