Having taken a few-minute perusal of it, my initial response would be "no." It seems very heavy on crunch, with little about the setting itself. If you're just looking to mine for adventure ideas, it doesn't seem to have much material.
It's possible that there's stuff in there that would be useful, and I just happened to miss it, though.
Most likely the 4e Eberron Player's Guide.There is almost no crunch in the campaign guide. The poster quoted above must have mistaken it with another book.

...ah, right. I was thinking of the player's guide.
As an aside, Jack, you could be less of a jerk about it.
All he said was that you were wrong. How is that being a jerk?
Back on topic, I'd say probably not. While the 4e ECG is a really nice book, if you've already got a lot of 3e stuff and you're not interested in 4e then I think you're golden.
