I hadn't seen this linked yet, and when I read it I thought it was likely one of the most thorough reviews on what varies and how when you're comparing cropped sensors to full frame or to each other.

There are obvious details missing, but at the 10,000 foot view this is all you'll ever need to know with regard to how the sensor size impacts everything from Focal Length to Depth of Field to ISO Noise to, well, stuff you probably haven't ever thought of. Best primer on it I've seen.
