It's OK, but I wouldn't live there. I think if you had a good solid month you could do everything worth doing, from snorkeling and surfing to history and culture. After that, meh. The whole state is very much like Las Vegas in that it is a tourist driven economy. Even their specialized agriculture (tropical fruits, etc) isn't spectacular per se.
Yeah, I was ready to leave after 2 months. But lucky me, I got to work 6 days a week out there, so we were lucky to see much outside of Hickam.
