Unity is set to be the default desktop in the next version of Ubuntu 11.04 'Natty Narwhal' and one thing that the Gnome desktop is missing in comparison to other desktop interfaces is native widgets this is something that Unity can include. Over the next 6 months the Unity interface is going to receive a lot of work to make it suitable for both desktop and netbook and I hope that this feature can be integrated into Unity at some point.
