Well, I'd put it this way, if you wanted to film the entire kid's Christmas concert, that's gonna make a big digital file you wouldn't be able to easily send to people digitally (I guess you could make them CDs if you have a CD burner) But if you wanted to film two minutes of the kid's solo, that you could easily manage with a digital camera and either upload or email to people.
