Yesterday, Mark Shuttleworth, the self-annointed Ubuntu benevolent dictator for life, unveiled a new user interface for Ubuntu called HUD, or Head Up Display. Whether it will be accepted or not is speculation, of course. It is innovative, especially in its integration of search within the CLI. Check out the video.
The two things that struck me most from watching the video were the CLI search capability and the search capability within applications. The search within applications seems similar to what we have now with Google desktop and Microsoft's desktop search, still it looks like it might be a little easier to use. Can't wait to check it out in April.
