I wasn't able to find an answer after a search, so I hope I'm not repeating a question, but why wouldn't I always have my camera (Xti) set to continuous shot instead of one shot?
It seems like it'd be a smart idea to always have continuous on in case you ever need it. Continuous seems to take single shots just fine, although I find that most people who are used to their slow point and shoots tend to fire off a couple shots by accident every time they try to use my camera.

i can shoot a single shot at 10fps (only 75% of the time though:rolleyes
