I don't think anyone thinks that every single copy will be perfect. I think what BillO and I take issue with is that the design is flawed, i.e., every single copy of the camera (or a very large batch) has the same problem.
The K-7 had a green line syndrome and a shutter blur problem. The latter was never addressed. The K-5 has less of a shutter problem but it isn't as good as the K20D (most likely because the engineers weren't aware of the K-7's problem and only somewhat accidentally reduced the problem for the K-5 probably in an attempt to make the shutter even quieter).
We all know the problems the K-5 had and has (the
FF problem is apparently not solved yet).
Cameras in the price bracket of the K-5 are supposed to be optical precision instruments. I think it is reasonable to expect respective performance.
Of course there are business realities and it probably was better for Pentax to get the K-5 out early in order to not have it appear as a "me too Nikon D7000" and lose a lot of sales to Nikon. But still, isn't the mentality to accept eroding product quality as having a mature approach to unchangeable realities, as a matter of fact, shaping the reality in undesirable ways?
It seems customers can only vote with their wallets so it appears entirely reasonable to me if they do.
