I may be a bit late on this but a little while ago i realized that Microsoft has released a preview verison of their Avalon and WinFX technology for Windows Xp and Server 2003. If you wish to try it out you can go to the following website and download it. [url]http://www.microsoft.com/downloads/details.aspx?familyid=C8F904E1-B4CA-402B-ACCF-AAA2BD60DA74&displaylang=en[/url]. Becarefule though this is only for Windows XP technonlogy. Personally i tired it and it is great though somewhat slow. The performance depends on your computer, and by the way this is a huge file (261 mg). Any way they will release the full and corrected version of the software addons when Longhorn comes out. Please notes take all warnings into consideration before you install this program becuase from my understanding it is irreversible unless you format which i had to do until i properly installed it. If your computer is a little on the slow side i sugges not installing this right now and wait until Microsoft releases its full anf functional version. Note this is only a preview.
