Windows Longhorn.

Can't wait for this to come out. I've heard it's pretty good from the people that are trying out the beta, just needs some of the bugs fixed. Anyone tried it to give us some info? Read on about it:
Windows Vista is the next version of Microsoft's Windows operating system, superseding Windows XP. It was previously known by its codename Longhorn, after the Longhorn Saloon, a popular bar in Whistler, British Columbia (see the other Microsoft codenames). The name "Vista" was unveiled on July 22, 2005. Longhorn Server, the successor of Windows Server 2003, is yet to be named. According to sources, the scheduled release date for Windows Vista is July 23, 2006. That release date is only scheduled for PC vendors so that systems will be made Vista-ready before Christmas. The general public availability is projected to be after early September 2006.
Windows Vista has several planned new features such as an entirely new user-interface called Aero, improved searching technology dubbed Search, and an XML specification designed for document formats and similar in many ways to Adobe's PDF entitled XPS. Windows Vista also has an entirely new development API, WinFX, along with several other key technologies. In addition, current speculation points to several different editions of Windows Vista being released, including starter, home, and professional editions. The new operating system had several previously scheduled features that are currently not planned to go into the operating system such as WinFS and the new command shell Windows Command Shell, code-named MSH and Monad. System requirements of the new software are also higher than previous versions of Windows.
