I agree the weather is nice, but a lot of folks I know who move there full-time often regret it. Some of the reasons:

1. Traffic is horrible in certain areas coupled with most cars driving a minimum of 30 mph under the speed limit (in the left lane).
2. Everything is expensive. Everything.
3. The "Haole" factor. (pronounced how-lee). Means that you are not a local islander (and at some point will be treated as such).
4. Many people taking the ethos of "moving at island time/pace)" to a whole new level. Do not expect services to be provided with any remote sense of punctuality. Everything is slowed way, way down. Can be cool for a bit (especially when escaping the rat race), but after awhile it simply becomes annoying.

With that said, I recommend visiting for a nice holiday. But as for full-time living.....?

Some folks also prefer Molokai because nobody goes there. Perhaps it is the " Welcome to Molokai, now please leave" sign which greets you as you leave the airport...er airfield.

Personally, I would continue past Hawaii a few more hours and visit the real South Pacific: French Polynesia, Tahiti, Fiji, Marqueseas, Vanuatu, etc.
The nature in Hawaii is beautiful, but you have to remember that it is in the US and with that comes the not so quaint restaurants in a strip mall atmosphere which has destroyed the islands. Honestly, I would rather not see a Costco, Kmart and TGI Fridays in some tan stucco shopping center. But to each their own.

Thanks for the article. Very interesting.
