Moving from a dev to live WordPress site?

If you’re like most website developers, you probably do most of your development on a subdomain (ie dev.domain.com) as opposed to the live site.

Welll, this is all fine and dandy until you need to move your nice, new WordPress site from dev.domain.com to www.domain.com — all of your images, links, site name, site domain, etc all have links tied to the dev URI.
