I think we can do better that the windows 7 UI .. remember how compiz murdered Areo. personally am not impressed with what i have seen or heard about windows 7. i mean vista was suppose to be the best thing since slice bread but look how that turned out. the last thing MS need is not another white elephant project that would be a drain on hardware. not now when netbooks play is big role in computing. for windows 7. keep it light.simple and allow for customization. and for Christ sake remove that god damn UAC. Windows 7 needs to do better than vista (which asks more question than it can solve) in term of user experience.
