I didn't crate train Oberon. Didn't (and still don't) see the need for it. I'm home all day, so was always able to keep an eye on him and keep him out of trouble and take him out when necessary. We did close off areas of the house with either closed doors or a baby gate when he was young, and then gradually opened it up as he got older. He's a real "sticky" dog anyway, so he's usually within a foot or so of us, anyway.
I think ultimately it depends on you and your family, as well as your lifestyle. I've seen here on the boards people who have had great success with dogs who've been crated. I've also known people IRL who've had puppies that they've expected to stay "good" in crates 8-10 hours a day -- obviously not a good idea, although it does beat leaving a dog outside without access to food or water for 8-10 hours a day (which I've, unfortunately, also seen).
