One more data point: I nearly always run the "right size" inner tube for the tire. On my randonneuring tires (700x30 or 700x32) I get about an average of 1 flat per 5000 miles. On my commute bike (700x23 tires until I finish wearing out the ones hanging in my basement) I get more like two or maybe even three flats per 5000 miles, but these are mostly pinch flats and occasionally splinter flats when I wear the tread too thin.
The one time I violated the rule about "right size" inner tubes was when I didn't have the right size inner tube for the tire (I had 700x23 inner tube for 700x28 tire). The inner tube lasted a week and was replaced with another of the same size. That one lasted about a week, too, at which point I figured out what was the problem and went out and got the right size innertubes. The inner tubes were stretched so thin that there was obvious wear in them, even after only a week. The inner tubes were probably cheapos, and the tires were extremely stiff Specialized Armadillos. I'd much prefer to know that I've got the "right size" inner tube in the tire, even if it takes me a minute or two more to run my fingers between the tire and rim on each side to double check that the inner tube isn't pinched.
