I also disagree. First, I have one and it surprises me how sharp it is at 300mm. It may not be as sharp as a prime lens, but it sure is pretty good and, to me, worth the trade-off for convenience of all-in-one performance. The attached image was taken at 300mm, the blow up has no additional processing, and nothing was done to enhance sharpness.
I have won contests with mine, and have photos I have taken with it published, so it can't be too shabby.
