After reading most of the threads, I'm still not 100% sure how come a cropped sensor (e.g. APS-C) can have advantages over an FF sensor in the bottomline, except for macro and other tele usage like bird shooting. And still, the abilities in macro usage can be discussed, because sensors may have pros/contras based on various criterias. For example if we compare 16.2 MP APS-C with 12MP FF, the fine detail in post-cropped image vs. the tonal & dynamic range produced by FF sensor...
OTOH, I think FF sensors are better in landscape photography even in terms of DoF because I can use smaller apertures before they become diffraction limited.

This is not true. If you select a SIMILAR DOF for both FF and APS-C, the diffraction softness effects on the image will be the same for BOTH formats. For FF you need to select a SMALLER f-value to get a similar DOF. And with that smaller f-value, diffraction effects on the image will be the same.

There are many wide angle lens choices (ok I admit it, a bit more expensive than the APS-C compatible ones but we left the budget out of the IQ discussion). One thing which can be mentioned on the negative side is the vignetting. Bu rather than "wide aperture vignetting", I'd say darker corners because of multiple filter usage on wider FLs. It's clear that using a FF compatible wide angle on a cropped sensor has it's advantages in terms of vignetting and IQ on the edges/corners. But if you pay the price, you'll get a better quality on FF...
Regarding portrait shots; no doubt, better subject isolation combined with sharper image (FF lens can be stopped down to get sharper image), go for the FF sensors.
So, all in all, except for the discussions regarding tele usage and (some) macro advantages, I personally cannot count any pros for the cropped format by means of IQ. But of course I'm still open for hearing the advantages of a cropped sensor. (I still did not sell my DX body yet...<img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/cool.gif' class='bbc_emoticon' alt='B)' />)
