From Mark's post: "We’re confident we’ll be able to retain the ability to run X applications in a compatibility mode, so this is not a transition that needs to reset the world of desktop free software. Nor is it a transition everyone needs to make at the same time: for the same reason we’ll keep investing in the 2D experience on Ubuntu despite also believing that Unity, with all it’s GL dependencies, is the best interface for the desktop." http://www.markshuttleworth.com/archives/551 http://www.markshuttleworth.com/archives/551 I don't see this as much of a threat, as long as they keep the compatibility until they realize that all those graphics effects are about as useful as 3d movies. Both the proprietary and free software worlds waste a lot of resources on that. Even minor GUI enhancements, such as the fact I can drag a window and it stays rendered instead of giving me a wire-frame TWM style, don't enhance useability much.
