After what I've seen, this UI is derivative of many bits and pieces that clearly have Nokia DNA. They've not tipped their hand at all, imho.

In fact, all they've accomplished was a show that they are working on something that might be worth the wait. From Bada to iOS to Android Gingerbread... those UI's are pretty much set in stone in so many different ways that Maemo/MeeGo wouldn't use.

And besides, the Moblin, now MeeGo for tablets has been out in plain view for ages.
