Which Hawaiian island should I move to?

I am currently in college studying communications in south Florida. My major encompasses a little bit of everything dealing with media (photography, video, web design, etc.). I plan on moving to Hawaii after college but I don't know which island. I love the outdoors and if it has to do with nature, chances are I enjoy it. Hiking is awesome but I'm also open to trying just about anything else there is to try. I prefer freshwater over saltwater so it'd be cool if there were some freshwater swimming holes around to use in addition to the ocean. I'm not huge into partying or nightlife. A good campfire suits me better than any club. But I also want there to be some places I can go to shop, eat, and hang out when I want to. I'm not made of money so something affordable is a must, although I don't need a huge, luxurious house or anything like that. A home close to the beach that gets me by is good enough for me. I'm very laid back and pretty much just go with the flow. Any suggestions and additional information on the islands would be great. Thanks!
