I just came by an interesting video blog (sorta) that discusses different aspects of Full Frame vs. APS cameras. It's CaNikon focused, probably does not have something quite new to most members here and some conclusion are debatable. However, I found it interesting and even though I'm not sure if I really learned something new, it was clarifying and eye-opening in some aspects. It's also a bit long for today's MTV generation at 40+ minutes, but well worth it IMO.
