Knowing exactly where to look makes finding an unknown much easier.
I patch tubes for routine flats whenever possible. For very small punctures, it tells me where to be looikng for that nearly invisible tire wire or tiny piece of glass or broken thorn, all of which can be entirely inside the casing waiting to cause the next flat.

Being a cheap bastard, I tend to patch also, maximum of three per tube. About the only real exceptions to that are my six bikes running sew-ups. Patching a sew-up is probably one of my least favorite tasks in the world. Fortunately, I tend to have good luck with them, and the inevitable puncture only happens once the tread is worn enough that I say to hell with it and toss the tire out.
