What's the big deal with full frame...
when "back in the day"
we all shot full frame and
printed 8 x 10?
When "back in the day"
zoom lenses were mostly crap...
we now have some superb super-wide and out zooms
we crop in camera when shooting!
The APS-C format has matured to become a great standard!
Everything about it is accessible...full frame will be bloody expensive!
Anybody?

With digital, every time you increase sensor size, you get a bump in performance (assuming the technology remains the same), So medium format outperforms 35mm outperforms APS-C with regard to high iso performance and dynamic range and so on down the line. There is a clear argument to be made that all of the cameras out there now are "good enough." If you own a K5 or a K30, you can probably shoot to iso 3200 without too much concern about noise and that may be adequate for your purposes, but clearly moving up to a larger sensor size will give a bump over those cameras.
The cost factor is a big reason why folks have chosen to go with full frame versus medium format. I think the Pentax 645D is about the cheapest medium format option out there now and it can be had for 4000 dollars, but unless you own lenses for it, you are talking several more thousand dollars to fill out your lens line up (and that is an older sensor that probably won't out perform current full frame sensors). On the other hand, there are full frame options now in the 1500 dollar range and the lens costs are much more reasonable.
APS-C is a great standard, but the biggest thing that has changed over time is that the cost of full frame has come down and folks with legacy lenses that cover 35mm sensor size start getting excited when it drops into their price range.
