MeeGo has NO potential. That is a fact, or at least it is made a fact by Nokia (for the moment at least). But at least listen to what Elop actually say: The N9 UI with Qt will be used on another platform, and it will be HUGE, the "next billion". That is the future. In all honesty, there really is nothing about the N9 UI that couldn't be done with any other core OS. Remember also the N9 is not running MeeGo core, it is running Maemo (whatever the difference may be).

The N9, confirmed to come in my local store in September has two cool features. The Design (materials and look) and the UI (Qt + ingenious simplicity and power). MeeGo is not even there.
