In February, the first Firefox OS phones will be available for developers to start testing with.

As an aside, I am still amazed at just how sucky most native applications are compared to their web alternatives. Case in point, why should I way 1 minute for the Wall Street Journal to download content into its native app, when I can read the same content instantly on the Web?

Beyond that and a few desktop replacements like Mail, Pages, or Keynote, there isn't much that would work just as well as a web application.
