ogling & comparing high ISO pics in web-sized viewing resolution is meaningless.
if small-res pics are enough to satisfy you, any cam can do it, and the k-7 will not let you down either. don't forget there's also NR settings available for you to tune up NR strength in-cam for k-7. if not, when bigger resolution is needed, it'd be better to leave things to the user, which the k-7 is doing. it's often at higher res that manual work will produce more desirable results.
many pictures when seen on your cam's screen look cool, but will shock you when it's opened in your computer at home.
since hitting the sliders is more or less inevitable, why not add a few clicks and do some noise reduction in post, then the k-7's strengths will show, in the form of better detail retention and greater flexibility
