I was only mentioning full-frame as those are the highest MP DSLRs available. I then mentioned APS cameras, which a lot of people do buy, especially the entry level stuff. In that segment and even in less than perfect light the higher MP cameras have been getting better, not worse. There's an argument to be made that if the manufacturers had stopped at say 12MP (to pick a number) and put all their effort into noise we would have better cameras now for the kind of use people actually put them through. In fact Nikon did just that at the high-end with the D700 and D3. There isn't however much of an argument to be made that the 16MP APS cameras of today are worse than the 12MP cameras of a couple years back. The latest models seem to have both more pixels and lower noise. Maybe you'd like a lower MP camera with even lower noise and maybe you can't buy it because MP sells cameras and thus shapes development. That could be a problem, but saying "excluding full-frame, more MP is actually worse" isn't really true. My impression is the complaints about MP are mostly right in compacts and everywhere else tend to be geek snobbery.
