Has Sony/Pentax/Canon fixed their non-working anti-dust systems yet?


Well, I don'' know about Sony or Canon, but the Pentax K10D doesn't
have an "anti-dust" system. It does have a two-stage 'dust reduction'
system (special coating and sensor shake) which helps to reduce the
problem of dust on the image sensor. And, in that regard, it works
very well indeed.
