A friend of mine bought the Fuji X10 over the Pentax Q and discovered the orbs.
He waited until the latest firmware fix but the orbs are still present. He has decided to take the Fuji back (within 30 day return policy) and is probably going to get the Pentax Q. I'll see him in a week or so, and will learn what his replacement pocket camera is.
I did get a chance to play with the Fuji and it is a pretty neat camera. Feels solid and the controls are convenient and easy to figure out.
According to DPReview many folks using the camera will hardly ever experience the orbs, but if you are an experienced photographer and you use the camera in all sorts of light situations the orbs are an going to be a problem.
By the way he already owns a Nikon D7000, he just wants a pocket camera for those times when a DSLR just won't work for him.
